Abstract
Nanotechnology may be a branch that deals with the size and tolerance of but 1nm (=one billionth of a meter), especially the manipulation of individual atoms and molecules. There are many applications and are varied, including energy production and storage, drug delivery, materials science and much more of others. The prefix ‘Nano’ is mentioned in a Greek prefix meaning dwarf’ or something very small and depicts one thousand millionth of a meter (10-9 m). We should distinguish between Nano science, and nanotechnology
Keywords
Atoms, Fabrication of macroscale products, Nanoparticles, Electronic properties
Introduction
Nanotechnology is the use of matter on an atomic, molecular and supramolecular scale for industrial purposes. The earliest, meaning of nanotechnology was mentioned as the actual technology goal of manipulating atoms and molecules for the use of macroscale products, also now called as molecular nanotechnology.
A more generalized meaning of nanotechnology was subsequently said by the national nanotechnology initiative, which defined nanotechnology because of the manipulation of matter with a minimum size of 1 dimension from 1 to 100 nanometers.
History
Nanoparticles and structures are employed by humans in early fourth century AD, by the romans, which discovered one of the foremost interesting samples of nanotechnology within the traditional world.
In 1857, Faraday studied the preparation and properties of colloidal suspensions of “Ruby” gold. Their unique optical and electronic properties make them a number of the foremost interesting Nano-particles. Faraday demonstrated how gold nanoparticles produce different- colored solutions under certain lightening conditions.
Modern Nanotechnology
In 2004, a new class of carbon nanomaterial’s called carbon dots (C-dots) with size below 10nm was discovered accidentally by Xu et al. during the purification of single-walled carbon nanotubes. C-dots with interesting properties have gradually become a rising star as a replacement Nano carbon member thanks to their benign, abundant and cheap nature.
After the invention of “grapheme” in 2004, carbon-based materials became the backbone of just about every field of science and technology. Nano-materials are already used in numerous products and industrial applications. They are not simply another step in the miniaturization of materials or particles. They often require very different production approaches. There are several processes to create various sizes of Nano-materials, classified as “top-down” and “Bottom- up”.
Nano-materials can be constructed by top-down techniques, producing very small structures from larger pieces of materials. They also can be built by bottom-up approach, atom by atom or molecule by molecule. One way of doing this self-assembly, in which the atoms or molecules arrange themselves into a structure due to their natural properties.
Conclusion
The progress of Nano science and nanotechnology in several fields of science has expanded in several directions, to watch things from micro to Nano, to even smaller scales sizes by different micro-scopes in physics, from micro size bulk interest small size carbon dots in chemistry, from room size computers to mobile slim size laptops in computing, and to watch the behavior of the cell’s nucleus to review single complicated biomolecules at the Nano level in biology.
Nanotechnology are getting used to create a replacement generation of solar-cells, hydrogen fuel cells, and novel hydrogen storage systems capable of delivering clean energy to countries still reliant on traditional, non-renewable contaminating fuels.
