The modern miracle. Nanotechnology.

Nanotechnology is a wonderful and almost miraculous field of science.

Nanotechnology is a word that is gaining popularity in society nowadays. It is used more frequently in science fiction than in the 1950s. The first thing that comes to mind when we see the word nanotechnology, we quickly associate it with some science-y industry or some futuristic application. But nanotechnology is actually more common than we realize.

One of the applications of nanotechnology in everyday items in it's application of smart lenses. The type of spectacle lenses that instinctively darken when exposed to sunlight. Nanotechnology is also used in the production of textiles that can make clothes stain-proof and wrinkle free. Nanotechnology is also used in pharmaceutical applications in the delivery of drugs to specific parts of the human body. Because of their small size, these nanites can flow in our bloodstream rather easily and deliver the drugs more eff

But of course there is always 2 sides to a coin. With the advent of nanotechnology also brings with it a new type of danger, Nanopollution.

Nanopollution is supposedly more dangerous and harmful than other cnventional types of pollution, as the nanoparticles are so small they can get virtually everywhere. For example tiny harmful nanoparticles can be easily breathed in by humans and cause us to get seriously ill or even result in death. Nanopollution is also harder to clean up compared to normal types of pollution as the nanoparticles are so small that they can't be easily detected or picked up.

Still, just because of these harmful effects should we not encourage research into nanotechnology? I say no. While the harmful effects of nanoparticles are very high, I believe that with proper handling of these nanowastes we can effectively control it. So I will encourage research into nanotechnology.
