It might seem far-fetched to talk about manipulation of matter at atomic, molecular or even supramolecular level - nanotech - but slowly the great minds of our time, using their incredible psychic powers, are pulling the phenomenon into reality. The impressive technical name “Nanotechnology” has attached to itself many magnificent marvels as tags in the ever expanding universe of science. Although, the first break through, under the ambit, came with the invention of 'scanning tunneling microscope' in 1981 which provided unprecedented visualization of individual atoms and bonds, the more recent scientific endeavors our even more marvelous and far more promising.
A futuristic concept of a nanobot deployed inside a body, tasked with the job of repairing Red Blood Cells
The Ohio State University has created a non-invasive chip that uses Tissue Nano transfection to alter skin cells into cells of any kind according to study. Researchers say it may be able to heal anything from nerve damage to brain injuries. It's only been tested on mice and pigs, but researchers hope to start clinical trials on humans in 2018. If all goes as planned we would soon be able to tap into the well filmed and imagined world of organic regeneration.
Earlier on, a study released in the journal Nature Communications details just how scientists are hoping to transform modern medicine with very tiny robots. The study features prototypes of Nano sized robots that could actually enter human bodies. While they haven't yet tested these little robots in people, they hope to do so soon. Perhaps, in the not too distant future, the Nano sized robots might do things that are too microscopic for doctors to currently perform and are too sensitive for common drug therapies to handle. The scientists modeled their robots on creatures in nature — the disease-causing bacteria African trypanosomes. The reason that these particular bacteria are the perfect models is because they have the unique ability to control their flagellum, the tail-like part of their bodies that helps them control their movement around the human body.
And that is not even close to the end of the Nano-tech chapter for it is not in any sense limited or confined to medical science in its applications. With the world’s population expected to exceed to nine billion by 2050, Nano tech might as well be amongst the best options we have if not the best to meet rising global demand for food, energy and water without increasing the strain on finite natural resources.
Nanotechnology allows the advent of super-strong materials like Carbon Nanotubes (CNTs) which have diameters of around 1 nanometer, even thinner than a strand of human hair!
However, like every other new endeavor, Nanotechnology research is still at an early stage though evolving quickly. However, before bringing Nano particles to the domain of applications, we need a better understanding of how they work and regulations to ensure they will be used safely. It's a risky game but "every new venture starts between hope and risk".
