What is Nano Technology?What is Nano Technology?

Scientific and technological advances that rely on the properties ofmaterials at a very, very small scale.Involves lots of complex concepts that are little difficult to understood.

“The design, characterization, production and application of structures, devices and systems by controlling shape and size of building blocks at the nanometer scale.”

NanoscaleRegion of greatest interest is 0.2-100 nanometres (nm).1 m = 1000 million nm, or 1 nm = 10-9 m
