Nanobots in Nanomedicine: now we can live forever!

NANOBOTS IN NANOMEDICINE NOW WE CAN LIVE FOREVER

Nanomedicine is a very interesting term. In fact, it is perhaps the most revolutionary breakthrough in modern medicine since the invention of aspirin. Nobel Laureate Richard Feynman had in 1959 declared that it would come a time when humans could move individual atoms around and control where they want them to bond and where they want to place them. Feynman had then said that if that is done, objects made from atoms (which include the human body) could be built, torn apart and modified in any way they want.

And that is just what nanomedicine promises to do. It could rebuild damaged cells one atom at a time or even create micro-robots that could manoeuvre around the arteries and inside the human body to look for pathogens and cancer and then destroy them. With that, the field of medicine will be changed forever.

Eric Drexler, one of the pioneers of Nanotech wrote the ‘Engines of Creation’ where he concurred on the concept suggested by Feynman. Written in the 1980s, he said that if the concept is materialized, it could repair all the damages in the body. He said that conditions like wounds, infections and diseases are due to the atoms being at the wrong places, then they can be put back into their rightful place and then the problem is solved.

The main object of nanomedicine is the nanobot. According to the Robert Freitas from the Institute for Molecular Manufacturing, the medical nanorobot is the ultimate tool that nanomedicine could offer. Made in the size of a bacterium, it would need to have its own energy source like motors as well as sensors that could guide its actions. On top of that, it would need its own in-built computer to know what to do when inside the body. The main difference with normal robots is that nanorobots will be extremely small, and tiny enough to go through the red cells of the blood.

Like it or not, medical nanobots will surely be the future of the medicine world especially in terms of curing known diseases and to extend human life expectancy. If everything is at its place, sometime around the 2020s would be the best time to bet on such advanced technology in medicine to appear for clinical trials.
