NAnoROBOTICS

NAnoROBOTICSNanorobotics is the technology of creating machines close to the microscopic scale of a nanometer

Nanorobots (Nanobots, Nanoids, Nanomites) would typically be devices ranging insize from 0.1-10 micormeters and constructed of nano scale or moleculer components.INTRODUCTIONNanorobot produce ultrasonic waves by passing a signal to the piezoelectric membrane

Nanorobot DesignApproaches to prepareNanorobotBottom Up Approach

Top Down Approach

A top-down technique that is closely related to Nanomanipulation involves removing or depositing small amounts of materialThe top down, semiconductor fabrication techniques are producing smaller and smaller structures-see for recent work. For example, the line width of the original Pentium chip is 350 nm. Current optical lithography techniques have obvious resolution limitations because of the wavelength of visible light, which is in the order of 500 nm. X-ray and electron-beam lithography will push sizes further down, but with a great increase in complexity and cost of fabrication. These top-down techniques do not seem promising for building nanomachines that require precise positioning of atoms or molecules.

Top down approachIn this approach assembling of atoms and molecules into functional components and systems is done

Bottom up ApproachBottom Up ApproachSecond Method

The other is based on controlled positioning of nanoscale objects, direct application of forces, electric fields, and so on

First Method

The first is based on self-assembly, and is a natural evolution of traditional chemistry and bulk processing

In the 3D workspace the target has surface chemicalsManufacturing better sensors and actuators- Nanorobot Control Design (NCD) simulatorThe nanorobots small Brownian motions to find the target by random searchThey monitor for chemical concentration significantly above the background levelNanorobots at the target release another chemical, which other use as an additional guiding signal to the targetRecognition of Target Site By NanoRobotBreaking up blood clots: Nanorobots could travel to a clot and break it upFighting Cancer: The robots could either attack tumors directly using lasers, micowaves or ultrasonic signals or delivering medication directly to the cancer site.Helping the body clot: One particular kind of nanorobot it the clottocyte, or artificial plateletParasite Removal: Nanorobot could wage micro-war on bacteria and small parasitic organisms inside a patient.Gout: Gout is the condition where the kidneys lose the ability to remove waste from the bloodstream. A nanorobot could break upt he crystalline structures at the jopints, providing releif from the symptomsMedical applicationThe robot swims through the arteries and veins using a pair of tail appendages
