What is Nanotechnology, Scope of Nanotechnology, How it can change our lives?
Today's blog topic is about Nanotechnology, This blog article will answers all the questions above.
It's a great innovation in technology and engineering and it has enormous scope in the upcoming future it will not only lower the electric waste but also will boost the innovation and flexibility of human being. Nanotechnology would be capable to give the same performance like the huge machine.
So let's dive into the main topic.
The pure gold in a wedding band creates a symbol of permanence and stability.
But medieval artisans knew that mixing super small amounts of glass with gold could create different colours and effects.
Their work is considered a primitive application of nanotechnology the art of manipulation matter a few atoms at a time.
Nanotechnology works on an almost unimaginably small dimension, using the nanometre, a billionth of a meter, as a basic measurement.
Substances often act differently on an atomic scale than they do in larger quantities when fewer atoms are at the surface of the overall structure and the forces of Newtonian physics come to dominate.
At the atomic level, magnetic and other properties can be exaggerated, bonds among atoms are stronger, and catalytic reactions become more dynamic.
Nanotechnology precisely engineers small groups of atoms and then assemble those groups into larger structures.
They foresee the treatment of tumours or genetic malignancies with "molecular machines" that root out bad cells or viral DNA sequence.
Researchers at MIT found that after severing the optic nerve of hamsters, an injection of nanoparticle peptides created a scaffold that allowed the severed nerve to regenerate and sight to be recovered.
Already, filters made with nanoscale particles are being used to purify drinking water.
The techniques used to manipulate materials at the nanoscale are not that different, conceptually, from those involved in everyday manufacturing.
Advances in microprocessor production the creation of thousands of circuits on silicon wafers through optical lithography or etching with the light already allows engineers to work at a scale of fewer than 100 nanometres.
It may allow even smaller-scale work if more intense light or x-rays are used.
Other nano techniques rely on small-scale chemical or physical processes to let material build up an atom at a time.
The way materials attract or repel each other at the atomic scale perhaps in the presence of a magnet or an electric current allows researchers to grow carbon nanotubes, for example, or quantum dots, which may prove useful in a variety of applications.
According to the National Nanotechnology Initiative, more than 800 products incorporate nanotechnology in some way, and rapidly advancing technology suggests that number will only increase.
