Uses of Nanotechnology

Have you ever wondered why nanotechnology is so popular and still continues to be a growing trend among venture capitalists and investors? What makes nanotechnology so popular that so many corporations want to venture into the nanotechnology business? Based on research and development for more than 20 years, nanotechnology certainly has benefited the society. Nanotechnology has helped improve and revolutionized some of today’s technology and has extended its uses in medicine, food, and even homeland security.

Nanotechnology can actually be found in your home. Polymer composite materials which can be found in tennis rackets, power tool housing, and luggage is derived from nanoscale additives. Those additives can also be found in cleaning materials and even in your daily shampoo. That’s how much nanotechnology has evolved throughout the years.

Nanotechnology is also used in electronics and communication devices.It makes faster and portable systems that can manage and store large files. You can thank nanoscale transistors for the memory of your laptop. Developers believe that in the near future everything can be stored in one single tiny chip. That’s how powerful nanotechnology is. One of the most important uses of nantochenology in electronics is the magnetic random access memory (MRAM) enabled by nanometer‐scale magnetic tunnel junctions that can quickly and effectively save even encrypted data during a system shutdown or crash, enable resume‐play features, and gather vehicle accident data.

There are also environmental applications for nanotechnology. It can be used for purification of the impurities of water so that cleaning water will be more cheaper. Paper towel is a new invention by develops that has the ability to absorb oil 20 times its weight. It is made with tiny wires of potassium manganese oxide called nanofabric.

National Nanotechnology Initiative (NNI) documents the advcancement of nanotechnolgy. In their website you can read the benefits of nanotechnology and its impact in today’s environment.

Food Nanotechnology

Nanotechnology is not only limited in the areas of biological molecules and engineering but it is also used now in the area of functional food. Although it is still a research and development study, food technologists are determined to innovate the potentials that food has in nanotechnology.

An overview of what is currently being researched, tested, and some applied in food technology:


One of the most important thing about the advancement of nanotechnology in food is because third world countries would benefit the most from it. Because of the limited supply of food there is an alarming decrease of its nutritional value. The quality is not that good and drinking water is not as clean as it should be.
