What is Nanotechnology?

When is it invented?

Why “nano”?

Where used?

How it builds our future?

Nanotechnology is a science where everything works in nano scale .

The first use of the concepts in 'nano-technology' (but predating use of that name) was in "There's Plenty of Room at the Bottom," a talk given by physicist Richard Feynman at an American Physical Society meeting at Caltech on December 29, 1959.

Why NANO !? It is better to question why not NANO ?

Inject nano robots into the patient

Detect cancer cell

Destroy cell

Do not effect on healthy cell

New research published in Advanced Functional Materials provides some of the groundwork necessary to one day develop mini-robots that could perform delicate tasks inside our body. As the thinking goes, these nanotechnologies would be able to swim in our bloodstream and even assemble medical devices inside our body.

The basic concept of pollution control on a molecular level is separating specific elements and molecules from a mixture of atoms and molecules . The current method for separating atoms is thermal partitioning, which uses heat to force phase changes

Making composite fabric with nano-sized particles or fibers allows improvement of fabric properties without a significant increase in weight, thickness, or stiffness as might have been the case with previously-used  techniques

Nanowhiskers that cause water to bead up, making the fabric water and stain resistant. Silver nanoparticles in fabric that kills bacteria making clothing odor- resistant.

Nanopores providing superior insulation for shoe inserts in cold weather. 

Nanoparticles that provide a "lotus plant" effect for fabric used awnings and other material left out in the weather, causing dirt to rinse off in the rain.

Nanotechnologies provide the potential to enhance energy efficiency across all brunches of energy industry and to economically leverage renewable energy production through new technological solutions and optimized production technologies.

Nanotechnologies provide essential improvement potentials for the development of both conventional energy source (fossil and nuclear) and the renewable energy sources like geothermal energy, sun, wind, water, tides or biomass

Nanotechnology involves manipulating properties and structure at nanoscale often involving dimensions that are just tiny fractions of the width of a human hair.Nanotechnology is already being used in products in its passive form, such as cosmetics and sunscreens.
