     Life without the word "NANO" would have been quite complex and unimaginable. Let us have an introduction about what is meant by the word "NANO"?  

What is meant by Nano?

 Nano is a prefix meaning "extremely small." When quantifiable, it translates to one-billionth, as in the nanosecond

nanomole; nanosecond".

What is Nanotechnology? 

Nanotechnology is the branch of technology that deals with dimensions and tolerances of less than 100 nanometers, especially the manipulation of individual atoms and molecules. (or)
In general terms "Nano-technology mainly consists of the processing of separation, consolidation, and deformation of materials by one atom or one molecule." Nanotechnology deals with dimensions and tolerances of less than 100 nanometers. 

Nanotechnology is a rapidly expanding field. It made our lives faster, smarter and easier to access any work we do. Without Nanotechnology our daily works would have been harder and complex than they are now.


What is Nano LED's?

A light-emitting diode is a semiconductor device that emits visible light when an electric current passes through it.

The NanoLED range is a novel and economical light source system that utilizes pulsed laser diode and light-emitting diode(LED) technology to generate short optical pulses over a wide range of repetition rates and wavelengths. 

Generally, we knew that nano LED's are used in T.V 's and computers to change the colour of the surface.

Colour changing surfaces:-

The surfaces which change from one colour to an another are said to be colour changing surfaces. We often see colour changing surfaces such as LED panels, LED street lights, and clothes.

The best example for a colour changing surface is a chameleon 

Uses of colour changing surface:- We use colour changing surface in many places in our real life. Such as, 

 1) Home decoratives

 2) In cars

 3) In computer (microchips)

 4) In traffic signals

 5) In medicine (to detect some harmful diseases by changing its colours)

 6) In army (gadgets which detect the moments of enemies

 7) for fashion ( clothes )

 

Present scenarios of colour changing surfaces:-

 The colour changing surfaces made cars, homes, and clothes look much better than they used to be.

Many entrepreneurs have started to show interest in the colour changing surfaces. Gradually, many startups have been started on the basis of colour changing surfaces.  People prefer colour changing LED lights and colour changing panels in their houses to change their mood. Other than homes they have much demand in medicine and in the army.
