Nanotechnology is the study and manipulation of matter at the nanoscale, with dimensions ranging from 1 to 100 nanometres. One billionth of a metre is a nanometre. The ability to design, manipulate, and fabricate materials at the nanoscale is central to nanotechnology. Nanomaterials are the name for these materials. Nanomaterials have features that are distinct from chemical substances of a bigger size. Properties of nanomaterials such as reactivity, melting point, fluorescence, mechanical strength, and electrical conductivity can all be changed at the nanoscale, making it difficult to predict how these materials interact with humans and the environment. Nanotechnology is one of the most essential technologies today, with applications in practically every part of our life. It creates solutions that are cheaper, faster, smaller, and stronger. Over the last 20 years, nanotechnology has had a dramatic impact on the production of innovative materials, and numerous new types of materials, such as nano-carbon, nano-silica, and nano-magnetics, are now available. These materials provide new opportunities for sophisticated device design (sensors, electronics, data and energy storage), as well as improved structural and functional materials.
