The arrival of Nano Technology might sound like kind of a blast of all the difficulties and the blooming trumpet of every new technology. The real meaning of the word nano is derived from a Greek word that means dwarf. Therefore scientists use this prefix to expose 10^-9. The nanoparticle is larger than atoms but much smaller to grasp from the naked human eye. The nanoparticle has specific characteristic features such as color, surface area, and catalytic activity.

“Nano Technology is an idea that most people simply didn’t believe”- Ralph Merkle

 Nano concept was firstly mentioned by  Prof.R.Feynman in 1959. This lecture is called “There is a lot of space down there”, Nowadays, this lecture is known as the origin of the nanotechnological era.

“Nano Technology” was introduced into the scientific world by N.Taniguchi at the international conference on industrial production in Tokyo in 1974.

E.Dexler developed the basic concepts of Feynman in his book ” Vehicles of creation: the arrival of the nanotechnology era” which was published in 1986.

Afterward, there was a considerable intensification of nanotechnological research and designs as well as publications increased sharply, A huge number of organizations were established, and many more countries were also involved in the process. Some of the research results could prove that along before the start of the present “nano era”,

For thousands of years, people knew about natural fabrics such as flax, cotton, wool, silk, etc. The nanoporous structure of natural fabrics possesses high utilitarian properties such as absorbing sweat well, quickly swelling and drying,

A research result of ancient Egypt which was conducted by Ph. Walter about a black dyed hair sample shows that ancient Egyptians used a dye that was made out of lime, lead oxide, and a small amount of water. Therefore it seems that they had used nanoparticles of gelatine(lead sulfide) without knowledge.

Some of the remarkable daily life applications are Batteries,fuel cells,solar cells,Memory,semi conducto devices,chips,sensors,functioning of cell,study of genes,pharmacy,fabric,garment

finishing, colour, fluids, polymers, particles, displays, lithography, photonics, forensics, punch machines etc.

Nanotechnology had made a new revolution and it has been the leading technology for the present crisis, Genetically modified (GM) foods are the best solution to overcome world hunger, gene therapy for hemophilia and Huntington’s disease, etc.

The recent discovery of “Nanobubble water” allows both freshwater fish and saltwater fish to live in the same water.

A Nanosensor probe called ORNL is another recent design through nanotechnology, it consists of a nanoneedle, Once it is withdrawn from the cell the ORNL nanosensor detects the signs of early DNA damage that can lead to cancer. Recently, a New biomaterial was designed for repairing damaged human tissue which doesn’t wrinkle when it is stretched. There is ongoing research that is hoping future tissue patches which have one or multiple layers, which are used to repair damaged heart walls, blood vessels, and skin. We can identify Thermopower waves which can cause powerful waves of energy to shoot through minuscule wires known as carbon nanotubes. It could lead to a new way of producing electricity.

This progress under this magical miracle is being made continuously and it’s not reversible.
