Nanotechnology has various applications in medicine, chemistry, environment, energy, and communication. Medical nanotechnology helps in diagnostics, drug delivery, and tissue engineering. Nanotechnology is used in chemical catalysis, filtration, and energy production. It also benefits communication by increasing computer memory and semiconductor speeds. Future applications could include improvements in data computation and laser displays.
Nanotechnology is the science and creation of materials at the molecular level. Applications of nanotechnology are used in medicine, chemistry, the environment, energy companies and communication. Whether through nanotechnology education or the application of nanotechnology, this science continues to evolve and finds more uses in everyday life.
The use of nanotechnology in medicine has provided many medical breakthroughs. Some of the applications of medical nanotechnology are for diagnostics. These are used to help identify DNA and help detect genetic sequences.
Other uses of nanotechnology in medicine are in drug delivery and tissue engineering. Drug delivery can help in cancer treatments by delivering drugs via implant as opposed to traditional injections. Tissue engineering is a new nanotechnology and involves the artificial repair or reproduction of damaged tissue.
The use of molecular nanotechnology in chemistry and the environment has already produced positive benefits. Chemical catalysis is a process of reducing pollutants using a reagent or catalyst. This can be especially useful when used in vehicle fuel cells or catalytic converters to reduce car emissions.
Filtration is another application of nanotechnology that can help the environment. Extremely small holes in the filtration, known as nanofiltration, remove ions for wastewater treatment or air purification. Slightly larger holes are used in a type of filtration called ultrafiltration and its current application is for kidney dialysis.
Many municipal energy companies are also nanotechnology companies because they use nanotechnology in their energy applications. One example is improved energy production through the use of solar cells. These solar cells currently convert only about 40% of the sun’s energy, but nanotechnology should be able to increase the amount of energy captured.
There are also studies investigating ways to increase battery life. These studies use nanotechnology applications such as supercapacitors. The intent is to reduce the number of batteries going to landfill and potentially contaminating groundwater and soil.
Communication has also benefited from the use of nanotechnology applications. Computer memory has been greatly increased and semiconductor speeds are much higher with further developments in nanotechnology. These improvements have led to advances in the speed with which information can be shared and the amount of data that can be analysed.
Without applications of nanotechnology, many of the laser displays used today would not be possible. The future of nanotechnology applications could also include further improvements in the speed of data computation. This would give computers the ability to perform large numbers of calculations simultaneously.
