This book provides an overview of nanotechnology, nanoparticles, and
nanomaterials. "Nanotechnology" refers to the branch of science and
engineering devoted to designing, producing, and using structures,
devices, and systems by manipulating atoms and molecules at the
nanoscale, i.e. having one or more dimensions of the order of 100
nanometers or less. The applications of nanotechnology can be very
beneficial and have the potential to make a significant impact on
society. Nanotechnology has already been embraced by industrial sectors,
such as the information and communications sectors, but in food
technology, energy technology, as well as in some medical products and
medicines. Nanomaterials may also offer new opportunities for the
reduction of environmental pollution.
