Plenary Speaker Systems Tamer Baar Member, US National Academy of Engineering Director, Center for Advanced Study Swanlund Endowed Chair CAS Professor of Electrical and Computer Engineering Professor, Coordinated Science Laboratory & Information Trust Institute University of Illinois at Urbana-Champaign Urbana, Illinois, 61801 USA basar1@illinois.edu Talk Title: Stochastic Dynamic Teams And Games With Asymmetric Information Abstract: In any real application of stochastic decision making, be it in the cooperative team framework or the non-cooperative game setting, asymmetry in the information acquired by different decision makers (synonymously agents or players) naturally arises. Presence of asymmetric information, particularly in dynamic (multi-stage) decision problems, creates challenges in the establishment of existence of optimal solutions (in teams) and non-cooperative equilibria (in games) as well as in their characterization and computation. No unified theory exists (such as dynamic programming or maximum principle) that would be applicable to such problems. In this talk, I will first discuss the intricacies that arise when one deviates from the standard framework of (neutral) stochastic control, through either restrictions imposed on controller memory or introduction of multiple agents acquiring and sharing information in a distributed manner and with delay. I will then discuss recent efforts toward developing a unified theory with regard to existence of solutions. For stochastic dynamic teams, the framework will encompass problems with non-classical information, for which the existence of team-optimal solutions will be obtained. For stochastic dynamic games with asymmetric information, the existence of Nash equilibria will be established using the newly introduced refinement concept of common information based Markov perfect equilibrium. Several examples will be provided to illustrate the approach, the solution technique, the underlying caveats, and the conditions involved. Some open problems, areas of application, and future directions for research will be identified.

KAUST Speaker Systems Jeff Shamma Professor, Electrical Engineering Jeff.shamma@kaust.edu.sa Talk Title: Humans-In-The-Loop: Adversaries And Allies Abstract: Recent years have seen tremendous research activity in control of networked systems, i.e., systems of distributed decision making components. This research has focused on decision making components that are engineered devices, e.g., sensors, swarm robotics, autonomous vehicles, etc. Many systems of interest are in fact a mixture of engineered devices and human users. Examples include shared airspace in transportation or consumer decisions in the smart grid. Unlike the case of engineered, and hence programmable, devices, a system designer cannot specify the incentives or the online algorithms that the components will execute. This presentation discusses two settings of humans-in-the-loop, namely competition and coordination. The first setting is resource utilization in the presence of an adversary under asymmetric information. Here, "asymmetric information" means that the system user has superior information over the adversary. In this setup, there is a tension between exploitation and revelation in that using advantageous information also reveals this information to the adversary. The talk presents a computational approach to derive optimal policies for the informed agent in the setting of repeated encounters. The policies can be interpreted as optimal deception through randomization. The second setting is inducing coordination among a collection of users. Here, there is a system planner that seeks to coordinate the behaviors of several system users. The challenge is that these users come with their own incentives. The talk presents a computational approach for the design of dynamic influence polices to induce coordination. The results utilize game theory throughout, specifically zero-sum games and mechanism design. Bio: Jeff S.

KAUST Speaker Systems Mohamed-Slim Alouini Professor and Chair, Electrical Engineering Associate Dean, CMESE Division slim.alouini@kaust.edu.sa Talk Title: Spectrum Scarcity And Optical Wireless Communications Abstract: Rapid increase in the use of wireless services over the last two decades has lead the problem of the radio-frequency (RF) spectrum exhaustion. More specifically, due to this RF spectrum scarcity, additional RF bandwidth allocation, as utilized in the recent past, is not anymore a viable solution to fulfill the demand for more wireless applications and higher data rates. Among the many proposed solutions, optical wireless communication or free-space optical (FSO) systems have gained an increasing interest due to their advantages including higher bandwidth and higher capacity compared to the traditional RF communication systems. This promising technology offers full-duplex Gigabit throughput in certain applications and environment while benefiting from a huge license-free spectrum, immunity to interference, and high security. These features of FSO communication systems potentially enable solving the issues that the RF communication systems face due to the expensive and scarce RF spectrum. The first part of the talk will give an overview of FSO communication systems by offering examples of advantages and application areas of this emerging technology. In the second part of talk, we will focus on some recent results and on-going research directions in the accurate characterization of the performance of FSO systems in the presence of inevitable impairments due to atmospheric turbulence and misalignment between transmitter and receiver. Keywords/Mots-clefs: Optical wireless communication, free space optical communication, atmospheric turbulence, pointing error, Gamma-Gamma fading, Lognormal fading, and capacity and error rate computation.

Special Invited Speaker Systems Hussein T. Mouftah Senior Canada Research Chair and Distinguish University Professor School of Electrical Engineering and Computer Science University of Ottawa, Ottawa, Ontario, Canada mouftah@uottawa.ca Talk Title: Smart Grid Technologies For Connected Electric Vehicles Abstract: Electrical power grid is among the critical infrastructures of a nation. In the past several years, the power grid operators have experienced several major blackouts which have caused large financial losses. In a close future, the imbalance between the growing demand and the diminishing fossil fuels, aging equipments, and lack of communications are foreseen to worsen the conditions of the power grids. For this reason, governments and utilities have recently started working on renovating the power grid to meet the power quality and power availability demands of the 21st century. The opportunities that have become available with the advances in Information and Communications Technology (ICT) have paved the way to this modernization. The new grid empowered by ICT is called as the smart grid. Moreover, in the near future, resilience is expected to become a more significant concern especially due to the additional loads of the Plug-In Electric Vehicles (PEVs). PEVs are expected to be widely adopted as passenger cars and as commercial vehicle fleets since they have low carbon emissions and low operating costs. In this talk we will address the challenges facing connected electric vehicles in a smart grid environment and provide some examples of smart grid technologies to mitigate these problems.

NSF Invited Speaker Systems Naira Hovakimyan Professor and University Scholar Department of Mechanical Science and Engineering University of Illinois at Urbana-Champaign nhovakim@illinois.edu Talk Title: Time-Critical Cooperative Path-Following Control Of Multiple UAVs Abstract: Worldwide, there has been growing interest in the use of autonomous vehicles to execute cooperative missions of increasing complexity without constant supervision of human operators. Despite significant progress in the field of cooperative control, several challenges need to be addressed to develop strategies capable of yielding robust performance of a fleet in the presence of complex vehicle dynamics, communications constraints, and partial vehicle failures. In this talk, we will present a theoretical framework for the development of decentralized strategies for cooperative motion control of multiple vehicles that must meet stringent spatial and temporal constraints. The approach applies to teams of heterogeneous systems, and does not necessarily lead to swarming behavior. Flight test results of a coordinated road search mission involving multiple small tactical UAVs will be discussed to demonstrate the efficacy of the multi-vehicle cooperative control framework presented.

KAUST speaker Systems Wolfgang Heidrich Director, Visual Computing Center Professor, CEMSE Division wolfgang.heidrich@kaust.edu.sa Talk Title: Computational Imaging And Display Abstract: Computational Imaging aims to develop new cameras and imaging modalities that optically encode information about the real world in such a way that it can be captured by image sensors. The resulting images represent detailed information such as scene geometry, motion of solids and liquids, multi-spectral information, or high contrast (high dynamic range), which can then be computationally decoded using inverse methods, machine learning, and numerical optimization. Computational Displays use a similar approach, but in reverse. Here, the goal is to computationally encode a target image that is then optically decoded by the display hardware for presentation to a human observer. Computational displays are capable of generating glasses-free 3D displays, high dynamic range imagery, or images and videos with spatial and/or temporal super-resolution. In this talk I will give an overview of recent advances and current challenges in rapidly expanding research area.

Plenary Speaker Materials David R. Clarke Member, US National Academy of Engineering Extended Tarr Family Professor of Materials School of Engineering and Applied Sciences Faculty Associate, Harvard University Center for the Environment Faculty Associate, Harvard University Microbial Sciences Harvard University, Cambridge, MA clarke@seas.harvard.edu Talk Title: Using Resource Availability In Selecting Materials And Biogenic Approaches To Expanding Resource Availability Abstract: Unlike many other electronic devices, the development of thermoelectric devices for utilizing waste heat has not matured enough to exclude the possibility of more sustainable materials compositions. In this talk I will describe a data driven performance and resource availability approach for identifying thermoelectric compositions as well as our work on using microbial methods for recovering and separating scarce elements. The latter is also applicable to other materials and devices, used in renewable energy devices. Bio: Its an exciting time to carry out research in materials. Not only do material scientists design and process new and improved materials but also materials now pace the development of many technologies, ranging from information processing to energy-efficient gas turbines for aircraft and electrical power generation. But what about materials for the future? How can we make sustainable materials when only limited supplies of critical elements exist on our planet? Since coming to Harvard, my group is carrying out long-term research in two new areas: using dielectric elastomers for energy conversion and soft robotics and using microbes to make, and recycle, materials. Dielectric elastomers behave as compliant capacitors: apply an electric field and they change shape. Alternatively, deform them and they will generate an electric voltage, very efficiently. (More details are given in the Research area of our web-site). Several energy materials materials that are critical to more energy efficient technologies consist of scarce elements, elements that have extremely low concentrations on earth. For instance, tellurium. It is used in CdTe solar cells and in many of the most efficient thermoelectrics, yet it is amongst the rarest elements on earth. In our group we are exploring the use of microbes to extract tellurium from existing devices and ores so that this rare element can be sustainably used for generations to come. Our research has also opened up the possibility of using microbes to grow films, such as used in solar cells, from earth abundant, non-toxic elements. Professor Clarke has been involved in many different materials research and development programs, contributing to ceramics, metals, composites and semiconductors, as well as introducing new approaches for studying the interrelations between microstructure and properties. He is author or co-author of more than 350 papers, holder of 6 patents, and a member of the National Academy of Engineering Web: http://clarke.seas.harvard.edu/

Bright Mind Speaker Materials Dr. Canan Dagdeviren Harvard Fellow, MIT/Harvard canand@MIT.EDU Title: A Flexible And Unusual Story: The Heart Meets Its Match Abstract: Implantable medical devices have made a major impact in improving healthcare. Increasingly in recent years, devices have become active rather than passive for example cardiac pacemakers. A key challenge for these active systems is their need for an internal electrical power source. A downside of present systems is the limitation of internal batteries, which must be changed frequently, requiring follow-up surgical procedures, with associated complication risks and additional healthcare costs. Energy harvesting, through chemical reactions, heat extraction, blood flow, and natural mechanical movements of organs, could help address energy depletion in implants. However, most harvesting units being considered today are like conventional batteries, in that they also rely on rigid electronics and subcomponents, and therefore, are incapable of providing intimate mechanical contact with soft tissue. In this study, a new class of biocompatible piezoelectric mechanical energy harvesters that enable high efficiency mechanical to electrical energy conversion from the natural contractile and relaxation motion of the heart, lung and diaphragm, demonstrated in several different animal models, each of which has organs with sizes that approach human scales are reported. A combination of such energy harvesting elements with rectifiers and microbatteries provides an entire flexible system, capable of viable integration with the beating heart via medical sutures and operation with efficiency of ~2%. These devices are first of its kind nano-generators that convert mechanical energy from internal organ movements into significant amounts of electric energy to power medical devices such as cardiac pacemakers. Bio: Canan Dagdeviren was born on 4th of May, 1985 in Istanbul, Turkey. Canan obtained her B.Sc. in Physics Engineering from Hacettepe University in Ankara. She was awarded with full-scholarship throughout her M.Sc. studies in Materials Science and Engineering at Sabanci University in Istanbul.

Rogers. Canans research experience focused on the applications of active piezoelectric materials and patterning techniques for unusual electronic devices with an emphasis on bio-integrated systems. Her collective Ph.D. research has implications across a variety of sensors and energy harvesting components for self-powered cardiac pacemakers, multi-functional cardiac vessel stents, non-invasive/wearable/epidermal blood pressure sensors, and skin cancer detection bio-patches. Canan received her Ph.D in August, 2014. Dagdeviren is currently a postdoctoral research associate in The David H. Koch Institute for Integrative Cancer Research of MIT, working with Prof. Robert Langer.

Bright Mind Speaker Materials Berardi Sensale Rodriguez Assistant Professor Electrical and Computer Engineering University of Utah berardi.sensale@utah.edu Talk Title: Graphene Based Terahertz Devices Abstract: Promising applications in many diverse areas of human endeavor, including medicine, biology, communications, security, astronomy, and so on, terahertz (THz) technology has recently turned into a very active area of scientific research. The THz frequency band, usually defined in the 0.1-30 THz range, was for decades one of the least explored regions of the electromagnetic spectrum, mainly due to the lack of materials and devices responding to these frequencies in a controllable manner. Even today, there exists a need for devices efficiently manipulating THz waves. In this talk I will discuss graphene as a material for THz devices and how its unique physical properties can be harnessed to develop novel high-performance active THz devices and systems. Several recently proposed THz reconfigurable devices based on graphene will be discussed. By employing graphene, an intrinsically 2D semiconductor as the active material, device design with unprecedented degrees of freedom, low-cost, and ease of fabrication is possible, thus leading to a substantial improvement with respect to the existing art in terms of controllability of THz waves. Although in the infrared/visible range the optical absorption of graphene is only a few percent and scarcely controllable, its optical conduc-tivity dramatically increases in the THz range leading to the possibility of electrical control of THz absorption. Moreover, by combining active graphene layers with other passive structures augmenting the intensity of the electric field in the graphene, the control over THz waves can be greatly enhanced. These devices can be employed as the building blocks for novel THz systems; for instance single detector THz cameras can be developed employing arrays of graphene electro-absorption modulators as electrically reconfigurable spatial light modulators.

Special Invited Speaker Materials Dieter Bimberg Foreign Member, US National Academy of Engineering Professor, Institute for Solid State Physics and Center of Nano Photonics Technical University Berlin, Germany bimberg@physik.TU-Berlin.DE Talk Title: Vertical Cavity Surface Emitting Lasers With Surface Nanostructures Abstract: Vertical-cavity surface-emitting lasers (VCSELs) are attractive low-cost light sources e.g. for optical interconnects e.g. in computer networks or optical sensors, providing high modulation bandwidth, lower power consumption, and symmetric beam properties. High-speed, energy-efficient, and temperature-stable VCSELs for data transmission with increasing link lengths have been demonstrated in the last few years. Nano scale photonic structures like high-contrast gratings (HCG) provide novel opportunities for VCSEL design and are expected to exhibit improved device performance like modulation speed, mode selectivity, and polarization control. Previous HCGs were designed with periodic boundary conditions using infinite-size plane incident waves. However, in a real device both the HCG and the incident wave are finite. Such modeling is presented here. The higher-order angular components of the finite-size incident wave are found to excite Eigen modes of the HCG causing reduced reflection and reduced reflection bandwidth. The in-plane and unidirectional transmission by the mode conversion in finite-size HCGs provide opportunities for novel applications like integrated VCSEL-based optical sensors and VCSEL-based on-chip optical interconnects.

Special Invited Speaker Materials Durgamadhab Misra Professor Electrical and Computer Engineering Department New Jersey Institute of Technology Newark, NJ 07102, USA dmisra@njit.edu Talk Title: High-k Gate Dielectrics For Sub-16nm CMOS Technology: Creating A Perfect Dielectric-Semiconductor Interface Abstract: Low power requirements by the International Technology Roadmap for Semiconductors (ITRS) dictate integration of high-k metal gates and novel devices such as FINFETs in CMOS technologies. To attend the current trend in device scaling for sub-16 nm CMOS technology (More Moore) EOT scaling of gate dielectric beyond 0.7 nm will be required. Various atomic layer deposition (ALD) methods of HfO2-based high-k gate dielectrics are currently underway to enhance the dielectric constant and reliability in order to meet the above requirements. For example, cyclic deposition of ALD Hf1-xZrxO2 samples where the dielectrics were exposed to intermediate slot plane antenna (SPA) Ar plasma (DSDS) or annealing (DADA). In addition, variation of Al percentage and distribution in HfO2 is carried out when HfAlOx and HfO2 are deposited by ALD in a layered structure. To further enhance the device performance, high mobility channel materials with high-k dielectrics are currently being integrated. Substrates like Ge and III-V materials are being considered for their high hole and electron mobility respectively. Electrical performance in these devices depends on the high-k deposition process, precise selection of deposition parameters, predeposition surface treatments and subsequent annealing temperatures. These variations in process conditions significantly impact the nature of the dielectric-semiconductor interface that controls the channel mobility. Interface passivation techniques such as nitridation, have limited success because of material incompatibility. This talk will outline some of the recent developments of EOT scaling of high-k gate dielectrics on silicon and how it impacts the interface; and the challenges of obtaining an acceptable interface for high-k on high mobility substrates.

KAUST Speaker Materials Jr-Hau (J.H.) He Associate Professor, Electrical Engineering jrhau.he@kaust.edu.sa Talk Title: Photon Managements By Employing Nanostructures For Optoelectronic Devices Abstract: It is of current interest to develop the photon management with nanostructures since the ability to suppress the reflection and light trapping over a broad range of wavelengths and incident angles plays an important role in the performance of optoelectronic devices, such as photodetectors, light-emitting diodes, optical components, or photovoltaic systems. Superior light-trapping characteristics of nanowires, including polarization-insensitivity, omnidirectionality, and broadband working ranges are demonstrated in this study. These advantages are mainly attributed to the subwavelength dimensions of the nanowires, which makes the nanostructures behave like an effective homogeneous medium with continuous gradient of refraction index, significantly reducing the reflection through destructive interferences. The relation between the geometrical configurations of nanostructures and the light-trapping characteristics is discussed. We alsoxc demonstrated their applications in solar cells and photodetectors. This research paves the way to optimize the nanostructured optoelectronic devices with efficient light management by controlling structure profile of nanostructures.

Industry Speaker Materials Scott Burroughs Vice President Technology Semprius, Inc. Durham, NC USA Scott.Burroughs@semprius.com Talk Title: Engineering A Path Forward For Low Cost Concentrator Photovoltaic Systems Abstract: Increasing system performance, reducing costs, and demonstrating long term reliability are currently the three most important focal points for CPV system designers. High manufacturing volumes are necessary, but not sufficient for reducing costs through economies of scale. What is required is a highly engineered solution to reduce the bill-of-materials cost while also increasing performance thus reducing the cost/performance ratio. The use of very small high efficiency multi-junction solar cells enabled by massively parallel transfer printing technology provides a step forward along the path toward low $/W. Further increasing the concentration ratio (>1600 suns) to reduce receiver costs and using transfer printing to mechanically stack multi-terminal >4-junction solar cells, relieving both the lattice matching and current matching requirements to increase efficiency and energy yield, offers an extension of that low $/W pathway. This approach promises to open up significantly more solar spectrum thus approaching the thermodynamic efficiency limit. Bio: Scott Burroughs is currently the VP of Technology at Semprius where he is leading the development of an innovative high efficiency, low cost Highly Concentrated Photovoltaic (HCPV) module for utility and commercial solar applications.

KAUST Speaker Materials Osman Bakr Assistant Professor, Material Science and Engineering SABIC Presidential Career Development Chair osman.bakr@kaust.edu.sa Talk Title: Remarkably Low Trap-State Density And Long Carrier Diffusion In Organolead Trihalide Perovskite Single Crystals Abstract: Along with the rapid progress in power conversion efficiency of perovskite solar cells, the key materials-based aspects behind the photovoltaic superiority of organolead trihalide perovskites are being vigorously pursued. However, the fundamental properties, and ultimate performance limits, of organolead trihalide MAPbX3 (MA = CH3NH3+; X = Br, or I) perovskites remain obscured by extensive disorder in polycrystalline MAPbX3 films. We report an antisolvent vapor-assisted crystallization (AVC) approach that enables us to create sizable crack-free MAPbX3 single crystals with volumes exceeding 100 cubic millimeters. These large single crystals enabled a detailed characterization of their optical and charge transport characteristics. We observed exceptionally low trap-state densities of order 109 to 1010 per cubic centimeter MAPbX3 single crystals (comparable to the best photovoltaic-quality silicon), which is ~ 7-order-of-magnetitude lower than nanocrystalline perovskite thin films. The low trap-state density leads to both superior photophysical and transport charachteristics of the MAPbX3 single crystals over nanocrystalline thin films. Exceptionally long photoluminescence (PL) lifetime, up to a microsecond time scale, and high charge-carrier mobility, up to a hundred cm2/Vs. was obtained in MAPbX3 single crystals. Charge-carrier diffusion lengths exceeding 10 m in MAPbX3 single crystals were calculated based on the measured PL lifetime and charge-carrier mobility. By revealing the intrinsic properties of hybrid halide perovskites here shown to be comparable to the best optoelectronic grade semiconductors and conditions for their high-quality growth, this study demonstrates that perovskite photovoltaics stand to see further breakthroughs through substantial improvement in material purity. The emergence of these intrinsically high-quality materials suggests new avenues to deploy hybrid perovskites in an even wider range of semiconductor and optoelectronic devices. Bio: Osman M.

Plenary Speaker Devices Dimitri Antoniadis Member, US National Academy of Engineering Ray and Maria Stata Professor of Electrical Engineering, MIT daa@mit.edu Talk Title: Evolution, Current State And Future Of Semiconductor Device Technology Abstract: The basic principles of scaling of MOSFET devices that are the core of logic electronics are reviewed. It is assumed that basic lithography and back-end (i.e. interconnect) scaling will continue well into the future according to their own roadmap and therefore only the aspects of FET dimensional and performance scaling are evaluated in this talk. Recent trends and research directions in performance boosters such as maximized strain in pure Si channels, new channel materials consisting of Ge, and Si/Ge and III-V heterostructures, and the required hi-k-metal-gate stack properties are surveyed and analyzed in context of device structures suitable for the 15-nm CMOS generation.

KAUST Speaker Devices Muhammad Mustafa Hussain Associate Professor, Electrical Engineering IEEE EDS Distinguished Lecturer Muhammadmustafa.hussain@kaust.edu.sa Talk Title: Lets Work On 22nd Century Electronics! Abstract: My talk title may sound too ambitious or too nave, but yes there is no harm in dreaming and to strive to realize that dream. The reason is simple: the influence of electronics and internet in our daily life will constantly increase. In the last decade we have observed the tremendous complementary growth of electronics and internet. In future they will be together as internet will be the soul of electronics to make them live (interactive). More importantly every object that we see or we will build will have such electronics to realize Internet of Everything. The range of spectrum for electronics will vary from high performance to harsh environment application. As of today there is no ubiquitous material or device which can serve all different purposes that are in demand. Nonetheless, one essential transformation we will see in all electronic materials and electronics are they will be tiny, light and thin. Definitely they are tiny and light today but are they all sufficiently thin? The answer is no and thats why we will see rise of ultra-thin film based electronics to make the overall system ultra-thin: super lightweight, extremely flexible, unimaginably reconfigurable and what not? Hence, I will show a few examples of processes to transform todays traditional electronics into ultra-thin electronics retaining their advantages (high-performance, low-power, thermal stability, CMOS process compatibility, ultra-large-scale-integration density, low-cost, long-term reliability) and adding attributes which we dont see today: flexibility, stretchability, reconfigurability. The range of applications we envision are didactic electronics (for existing objects) to embedded electronics (for objects we will build in future). Isnt it great that all our objects are interacting with us for a smart living and a sustainable future?

It is extremely challenging to maintain efficient electrostatic control by the gate in ultra-scaled devices due to the encroachment of source/drain electric fields, leading to increased leakage. Moreover, the most effective knob used for lowering power, namely the power supply voltage, cannot be scaled as rapidly as in earlier technology generations, thereby making the devices very energy inefficient. This arises from the inability to simultaneously reduce the threshold voltage due to the 2.3kT/q = 60 mV/decade fundamental lower limit of the subthreshold swing (SS) (inverse of the subthreshold slope = dlogId/ dVgs) for MOSFETs. In this talk, I will discuss the exploration of novel 2D materials (MoS2, WSe2, etc.) for obtaining improved electrostatics and Tunneling Field Effect Transistors (T-FETs), employing a fundamentally different mechanism in the form band-to-band tunneling for overcoming the fundamental limitations of MOSFETs. This tailoring of both material and device technology can lead to transistors with steep SS which is crucial for obtaining high energy efficiency and ultra-scalability. While transistors with steep SS have mainly evolved with an aim of reducing the power consumption in digital electronics, I will show that, they can also revolutionize a completely diverse arena of sensor technology. I will illustrate that biosensors based on TFETs can lead to unprecedented performance improvement compared to that of conventional electrical biosensors, with around 4 orders of magnitude higher sensitivity and 10x lower detection time. I will also report the unique advantages of MoS2 as a material for electrical biosensor that it offers ultra-high sensitivity surpassing that of graphene by more than 74 fold and at the same time is highly advantageous for single-molecule detection.

Special Invited Speaker Devices Jackie Y. Ying Institute of Bioengineering and Nanotechnology 31 Biopolis Way, The Nanos, Singapore 138669 Talk Title: Advanced Nanosystems For Diagnostic Applications Abstract: Our laboratory has been developing various nanosystems for diagnostic applications. These include designing plasmonic nanocrystals for single nucleotide polymorphism (SNP) genotyping. The platform involves polymerase chain reaction (PCR) for target sequence amplification and colorimetric detection for pharmacogenomics applications. We have also established polymer-based lab-on-a-cartridge for automated sample preparation and PCR detection. The integrated all-in-one system, termed MicroKit, allows for the rapid and accurate typing and subtyping of influenza and other viral infections within 2 hours. We have created the silicon-based Microsieve system for rapid and selective isolation of circulating tumor cells (CTCs) from peripheral blood. This non-invasive, near real-time, inexpensive liquid biopsy approach allows for the enumeration and biomarker analysis of CTCs for cancer diagnosis, prognosis and monitoring. Bio: Jackie Y.
