Nanoscience and Nanotechnology are the study and application of minuscule matter and can be used across all sciences, including chemistry, physics, biology and engineering among other scientific fields. The case is then manipulated on a molecular, atomic and supermolecular scale. The dimensions used in this science are Nanometers(0.1-10). To understand just how tiny a Nanometer is, 1 inch has 24,500,000 nanometers while a single newspaper page is around 100,000 nanometers thick.

Nanotechnology is used to make tailor-made particles, which are then used to make other products from medicine to sports gear. This field is not well known compared to other Sciences.

Current Nanotechnology use

The current plans that are underway for Nanotechnology use in biology are to prevent diseases by introducing nanoparticles into the bloodstream as microscopic robots. The nanobots can search for conditions, mostly terminal. They then report back to a computer and automatically secrete defective tissue, which then stops the disease from further spreading. Some scientists even believe that this technology can prevent death itself.

In preventing aging

As human beings age, cells which use to reproduce, slow down or stop altogether. Organs of the body start losing some functions, gray hair sets in, wrinkles appear and the skin becomes less elastic.

What happens at this stage is that when a cell dies, our DNA replaces it immediately. There is a problem, though. Our bodies do not produce exact copies. As the copying process to replace dead cells continues, so many details are lost, and the result is age. That is the reason when a person ages, they look entirely different from how they were before.

With the use of nanotechnology, scientists believe that the natural aging process can be stopped altogether. The idea is to introduce Nanoparticles into the human body so that the cells come out as exact copies. Also the nanorobots will report on any threats in the form of the disease or organ failure and fix the situation on the spot.

Nanoscience a derivative of many sciences

According to Ray Kurzweil a computer scientist, engineer and winner of the US National Medal of technology, biotechnology and nanotechnology will be combined to manipulate atoms and molecules and stop the aging process. He also states that anybody who will live to see 2050, will have a very high chance of living longer by up to ten times. By then, research would have been completed, and the results would be out.

Interest is huge

A lot of interest has been stirred up by this technology, and many countries are currently pursuing the research which is also well funded. The US has poured around $4 Billion, Japan approximately $1 Billion and Europe 1.2 billion.


As with every new technology, there is always the flip side of the coin. Critics think that we are already overpopulated. Do we really want to live longer and will planet Earth be able to cope? Will this technology just work for only those with means while the rest are left to die?
