Applications of Nanotechnology: A Review

International Journal of Advanced Research in Chemical Science, 2020

Nanotechnology can be the possible solution to the problems which are related to humans having to do with the vital needs and wishes for sustainable living. The vital needs of humans are food, water, energy, clothes, shelter, health and clean surrounding conditions. The wishes for lavish life include understanding and achieving computerization in each and every field such as space travel, increasing life expectancy. Due to continuous efforts of scientists and engineers during the last thirty years, there is substantial progress in different sectors such as agro, food technology, water purification, automobile, energy storage, cosmetics, cloth and fabrics, construction material, etc. Nanotechnology involves R&Don the atomic, molecular or supramolecular levels in the range of approximately 1-100 nanometres to give us a fundamental and basic understanding of phenomenon and composition. The nanometre-scale can be compared to the billionth part of a meter. In analogy, a human hair is in the range of 10,000 nanometres in diameter. Nanotechnology is used to create structures, devices and systems that have enhanced properties and functions because of their decreased size. The matter shows unusual physical and chemical properties due to the increase in surface areato volume ratio as particles get smaller in size & this is called quantum size effect. This means the bulk properties of materials at the nanoscale can be very different from those at a larger scale. Taking advantage of these characteristics of the material, scientist designs and produces devices by tweaking the shape and size at the nanoscale with wide-range of implications which could include medicine, electronics, military applications, computing, space science and many more. 1.1. HISTORY The concept of nanotechnology first came into existence from a talk given by physicist Richard Feynman titled "There"s Plenty of Room at the Bottom," at an American Physical Society meeting at Caltech on December 29, 1959, who pictured that the entire Encyclopedia Britannica could be printed in the head of a pin. The term "nanotechnology" was defined by Tokyo Science University Professor Norio Taniguchi in a 1974 paper as follows: ""Nanotechnology" mainly consists of the processing of, separation, consolidation, and deformation of materials by one atom or by one molecule." Even though scientists have been working with nanoparticles for many years, most of the research work done was restricted by their inability to see nanoparticles itself. Hence, long before STMs and atomic force microscopes were invented Feynman pitched this revolutionary idea to his colleagues. As determined in his quote (above), he chose to end with a "final question" that wasn't fully realized until the "80s and "90s. Finally,then, it was during these two decades, when the term "nanotechnology" was coined and researchers, starting with Eric Drexler, built up this field from the bedrock that Feynman made in 1959. But, some researchers such as Chris Toumeyneglect the gravity of Feynman in the formation of the intellectual breakthrough for nanotechnology.

A Review of new and emerging applications, issues and future aspects of Nanotechnology

Nanotechnology is a new approach that refers to understanding and mastering the properties of matter at the nano-scale: one nano-meter (one billionth of meter) is the length of a small molecule. At this level, matter exhibits different and often amazing properties and the borders between established scientific and technical disciplines fade. Hence the strong interdisciplinary character that is associated with nanotechnology.

The Emergence of Nanotechnology and its Applications

Nanotechnology deals with the application of nano-sized particles in the range of 1 to 100 nm, and due to their sizes they exhibit unique properties which enhance a wide range of utility in various field of application.
