Nanotechnology refers to the use of atomic matter for industrial purposes. Nano in size refers to the billionth of a meter. It is used in different applications like nanoelectronics, biomaterials, medicine, real estate, and other advancing fields of science. Nanotechnology is said to have found its route by one of the greatest physicists of all time Richard Feynman at the American Physical Society in 1959. Nanotechnology aims to make huge strides in science as it increases the strength of materials and enhances the working of many devices. Besides, it also helps in renewable energy production, as seen in current times.

However, the most significant impact of nanotechnology is in the field of pharmaceuticals, where it helps develop those medicines to target small areas generally left untouched by normal medicine. One of the greatest progress in such an area is the treatment of cancer cells using nano knives. However, the field has a potential for newer studies and discoveries, and hence a lot of progress has to be made in this field in the coming times also. 

Currently, many threats to it, including security, privacy, etc., are not taken care of; however, with time, regulations have to be developed for its secure usage. Nanomaterials have unique properties that determine their physical, chemical, and biological behaviour. It is one of the fields of science that is very popular in colleges, schools, and universities in current times.
