WHAT IS NANOTECHNOLOGY ?

Nanotechnology is the science of manipulation of matter according to our need at the Nanoscale of the order of 10^-2 . it have tremendous possibilities in near future because of its ability of making advance material  with unique chemical property which suits according to condition   . 

This term technically first time introduced by physicist Richard Feynman in 1959 in his lecture with topic of There is plenty of room at the bottom . but at that time technology was not enough to implementation of his idea in practical application's .

Primarily there is two type of approaches we use to construct anything  -

I)  Top-to-bottom approach 

II) Bottom-to-top approach

Top-to-bottom approach :- when we cutoff resource to make our desirable shape is known as Top-to-bottom approach ; Ex- wooden chair . 

Bottom-to-top approach :- when we construct structure by starting from its minute cells to approaching required shape of structure is known as Bottom-to-top approach ; Ex- buildings .

Nanotechnology belongs to second type of manufacturing approach (Bottom-to-top) in which start making structure at very tiny scale from 1nm to 100nm which exhibit very advance property concerning with the task . which ultimately offers perfect shape and size with required chemical properties without wasting further ingredients like usually happens in Top-to-bottom approach .

Nanotechnology not remained theoretical science concept anymore due to today's advance technology we already started making material at that tiny scale which are quiet useful for day to day life , with the help of Nanotechnology we can make such cloth's which could act like hydrophobic . 

With the help of nanotechnology we are able to make nanobots which can cure particular  area of human body instead of using conventional way of treatment which will increase efficiency of treatment and speeds up improvement in patient health and will give quick relief .   

 

Nanotechnology is widely considered as next revolution in history of human kind , in fact we  started using Nanotechnology already there are hundreds of Nanotechnology product are commercialized and in every three to four weeks at least one Nanotech product are about to make debut in market  .

Although Nanotechnology have power to change our world entirely it also have some drawbacks - 

- it could also be used for bad motive's .

- material's manufactured with the help of nanotechnology are toxic in nature .

Some specialist also thinks that nanotechnology will rise unemployment because of automated machinery less with artificial intelligence manufactured by nanotechnology will effect job opportunities but in my opinion this new technology of Nanoscale will surely decrease job opportunities of one kind and will generate job opportunities of other kind .
