Basic Things You Should Know About Nanotechnology

There are many new technology today. And one of them is nanotechnology. Have you heard about it before? If not, nanotechnology has so many benefits which you need to be aware of. Before letting you know about the applications of this technology, let’s define what nanotechnology is.
Meaning of nanotechnology
Nanotechnology was derived from two words, nano and technology. Nano means one-billionth of a meter. And technology is defined as the act of using science in science and engineering to invent useful things that would solve problems easily. By combining the two words, nanotechnology means any technology that makes use of very small materials whose size is about one-billionth meter.
The Center for Responsible Nanotechnology explained nanotechnology as the ability to create full and high-quality gadgets from the smallest available molecular particle. This creative ability is used to invent high-tech appliances which cuts across several science fields such as engineering, physics, biology, and chemistry.
Applications of Nanotechnology

  • Cheap water treatment: Nanotechnology has found its way into redeeming us from environmental hazards. Nanoparticles act on pollutants of industrial water by killing germs and removing particles in it. This process is cheap, safe, and more efficient than the conventional method of pumping water from the ground before treatment.
  • Advanced security: With this technology, the military, government agencies, institutions, and business can now defend themselves. With the emergence of nanotechnology, institutions and organization now have microscopic video and audio recording devices for surveillance. Military and government security agencies also make use of nano robots for rescue operations in hazardous zones.

Disadvantages of nanotechnology
The advantages of nanotechnology make life easier for us all. However, it has some disadvantages that pose as threats to our environment. Some of the disadvantages of nanotechnology are as follows:

  • Productions of destructive weapons: The application of nanotechnology in producing weapons is still in the works. And if this technology is perfected on a commercial scale, the whole world would be at risk of weapons that are highly destructive. For instance, the newly developed “smart bullet” is a computerized nano bullet that has 99% accuracy. If such bullet gets into the wrong hands, it can cause massive destruction.
  • Imminent health hazards: Nanofibres are used for producing wound dressings and textiles used for surgeries. However, the sizes of the fibers make it easy for them to escape into the atmosphere. And they can easily be ingested by unsuspecting persons. Furthermore, there is the fear of the fibers causing critical health challenges such as cancer if they are ingested in large quantities.

Bottom Line
The above are the basic things about nanotechnology. There are still more research and development going on in this field. If you are interested in knowing more about nanotechnology, you can read more at Nanowerk and Center for Responsible Nanotechnology
