The expression "Nano" originates from Latin word importance Dwarf. Furthermore, in academic group it alludes to 1nanometer.
1nm = one millionth of a mm
1nm = one billionth of a mm
The expression "Nanotechnology" was utilized surprisingly by Richard Feynman in 1959 in his article
"There is a lot of room left at the base".
The expression "Nano science" was first characterized by Japan researcher Norio Taniguchi.
Nano Science is a field of science which is worried about investigation of particles, atoms and articles whose size is on Nano meter scale.
Note: Materials carry on diversely at nano meter scale than when contrasted with when they act
at the ordinary scale.
For ex: Gold at full scale is artificially inactive however at nanoscale, it carries on as an impetus.
The purpose behind this is the adjustment in the central property of issue because of the expanded proportion of surface range to volume which prompts adjusting the physical, warm and synergist properties of matter.
Ways to deal with Nano Technology
Bottom-up
Materials and gadgets are worked from the sub-atomic parts which collect themselves
artificially by standards of atomic acknowledgment.
Eg: Carbon nanotubes assembled utilizing Graphene.
GRAPHENE: it is a substance made out of unadulterated carbon where the length of carbon securities is 0.142nm. The molecules in Graphene are orchestrated in a hexagonal example like honeycomb structure.
The term Graphene was begat as a mix of graphite and the addition "ene" by hans-dwindle Boehm.
Note: The Nobel prize in Physics for 2010 was given to Andre Geim
what's more, Konstantin Novoselov for momentous trials as to material Graphene.
Graphene conducts power speedier than silicon. It can likewise oppose temperature
Upto 150 degc. Thus it has turned out to be favoritly utilized as a part of IC's and PC sheets.

As the name proposes, nano objects are developed from bigger substances.
Ex: Gold at large scale is artificially idle. Yet, at nano scale it goes about as an impetus.

Uses of Nanotechnology
1. Nanoparticles
These are minor particles that have uncommon properties that are utilized as a part of a few territories which has high centrality.
For eg: Nanoparticles of Titanium dioxide is utilized as a part of some suntan salves and beautifying agents.
These modest particles are straightforward on skin and can ingest and reflect UV beams.
2. Nano drug
It is the field of innovation where Nano materials and gadgets are intended for restorative
motivations behind
Diagnosis
Prevention of sickness
Treatment of damage
Drug conveyance
Bioavailability of medication
It is the exploration of guaranteeing the nearness of medication particles in the ideal place of the body with consummate measure of pharmaceutical where it will do generally great.
Nano Pharmacology
It is the science which includes connecting up of manufactured nanomaterials to organically dynamic
mixes or atoms to be utilized as tests and medications to distinguish and target strange cells.
Nanorobots
Therapeutic nanorobots would circle unreservedly all through the body when infused into the
circulation system. These would convey drugs which will be specifically discharged on coming in
contact with the unusual cell.
3. Military applications
Bio-restorative architects are endeavoring to create nano-mechanical olfactory sensors (NOSE) to
recognize trademark substances.
Keen tidy might be conveyed for stealthy checking of a threatening situation.
Potential risks because of Nanotechnology
Commentators of Nanotechnology indicate the potential harmfulness new class of nano substances that
might modify adjust both biologically and for a man exclusively.
Researchers term this as Nano Pollution.
NanoPollution
It is the bland term given for all waste created by nanodevices or amid the nano-
material assembling process.
Ex: Nanoparticles of Titanium dioxide that is utilized as a part of sunscreen moisturizers and beauty care products can get
into natural way of life and cause maturing of colon cells.
Cadmium selenide nanoparticles can cause cadmium harming.

Nanotechnology in India
Branch of IT has begun the Nanotech improvement program. A dream bunch under the initiative of CNR Rao was setup and depended with the undertaking of defining a National Nanotechnology Policy.
The legislature of India additionally has propelled the Nanoscience and Technology activity. A
program that spotlights on general R&D in Nanotech field with the goal that India can be a noteworthy Player in nanotech in years to come.
