What is Nanotechnology?
Nanotechnology is the manipulation of matter at the nanometer scale (1–100 nm) to create materials and devices with novel properties arising from their extremely small size. At this scale, quantum mechanical effects become significant and surface-to-volume ratio becomes very large, giving nanomaterials properties distinct from bulk materials. Chemistry plays a central role in nanotechnology through synthesis of nanoparticles, nanotubes, and other nanostructures.
