Applications of nanotechnology
Résumé
The applications of nanotechnology, commonly incorporate industrial, medicinal, and energy uses. These include more durable construction materials, therapeutic drug delivery, and higher density hydrogen fuel cells that are environmentally friendly. Being that nanoparticles and nanodevices are highly versatile through modification of their physiochemical properties, they have found uses in nanoscale electronics, cancer treatments, vaccines, hydrogen fuel cells, and nanographene batteries.
Nanotechnology's use of smaller sized materials allows for adjustment of molecules and substances at the nanoscale level, which can further enhance the mechanical properties of materials or grant access to less physically accessible areas of the body.
Nanotubes can help with cancer treatment. They have been shown to be effective tumor killers in those with kidney or breast cancer. Multi-walled nanotubes are injected into a tumor and treated with a special type of laser that generates near-infrared radiation for around half a minute. These nanotubes vibrate in response to the laser, and heat is generated. When the tumor has been heated enough, the tumor cells begin to die. Processes like this one have been able to shrink kidney tumors by up to four-fifths.
Ultrablack materials, made up of “forests” of carbon nanotubes, are important in space, where there is more light than is convenient to work with. Ultrablack material can be applied to camera and telescope systems to decrease the amount of light and allow for more detailed images to be captured.
Nanotubes show promise in treating cardiovascular disease. They could play an important role in blood vessel cleanup. Theoretically, nanotubes with SHP1i molecules attached to them would signal macrophages to clean up plaque in blood vessels without destroying any healthy tissue. Researchers have tested this type of modified nanotube in mice with high amounts of plaque buildup; the mice that received the nanotube treatment showed statistically significant reductions in plaque buildup compared to the mice in the placebo group.
