Nano Technology

Nano technology

we have seen sci fi movies where we see plateles and red blood corpuscles rushing up and down with the hero and the heroine!
Is it possible in reality today?
Yes ,amazing to hear isn't it!
No doubt about it.
Instead of the hero and the heroine we can have miniature robots rushing your blood stream!
They can do amazing work like mending your skin or wounds or making a new organ for you when you are asleep.
Doesn't it sound crazy?
But today man has the ability to create and use such docile robots which help instead of waging a war against as shown in the movie “Terminator “.
How is this amazing feat of human advancement achievable?
It was once stated in 1959 by Richard P Feyman that we would create robots that would in turn create arms 1/10th of its size which would inturn create arms 1/10th of their size and so on.
This is called nano technology i.e building miniature robots which can be used and controlled to build objects at molecular level.
It is also building objects and products bottom up,other than our conventional top down methodology used for product assembling and building.
The science of tiny molecules, is a magnificient achievement in human history, a very important aspect for modern life. The fields like biotechnology, electronics, energy and industrial products are using it a lot.
Nanotechnology is also about using the technology to use particles of that size for administering medicines too.
The recent noticable applications are in wind shields for protecting from UV rays and in dirt resistent clothes.
In a recent Hindu article an exibition was shown.
Many glass boxes were placed with big gizzmo lenses to see through the exhibited objects.
A nano guitar, nano car, nano bikes, nano planes, nano eiffel tower were a few among the 121 participants in the exhibition.
Here are some of the pictures that were shown in the exhibition.



Nano copper particles Nano sphere Nano zinc particles
Also the latest improvements are molecules washing dirt off clothes, robots repairing Integrated circuits, molecules destroying cancerous and bacterial cells.
But look at the dark side where there are many places where this can be misused.
What happens if the nano particles cross into in intended boundaries of cells and interfere with other metabolic activities?
When you talk at nano level even the elements like gold and platinum become reactive.
So what happens if a person sends a spray into our gold reserve and all are converted to nothing in seconds?
We should have some ethics listed and grounded at that level too to use such effective and sharp technologies in day to day life, so that the dark side of humanity dont miss use it.
In future, probably in a couple of decades like when we are in our mid forties, we would be using millions of such robots and particles which would live inside our body with us eat and drink with us and help us to live a very long life!
But Beware ! Even a mice scares an elephant away!
