The biomedical applications of carbon nanotubes (CNTs) is deliver drugs directly to the targeted cells and tissue. The characteristics of these materials such as biological properties, unique chemical, shape, hollow monolithic structure allows the materials to enter the cell via passive diffusion across the lipid bilayer or their ability to obtain the desired functional groups on their outer layer. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3230565/
Researchers use nanoparticles to send chemotherapy drug directly to the tumor site- Patricia Picazo Scientists from the California Nanosystems and the Comprehensive Cancer Center at UCLA, have developed a system that sends one particular chemotherapy drug directly to the tumor, which greatly reduces the side effects of the drug and increases its effectiveness. They use mesoporous silica nanoparticles to deliver the drug to the tumor instead the drug circulating through the blood stream. The drug is located inside particles that are wrapped with lipids and once the particles reach the site, they release the drug, based on the acidity of the cancer cells. Although it is still in mice trials, they hope that soon the technology will be used in humans. http://phys.org/news/2016-03-nanoparticles-chemotherapy-drug-tumor-site.html
Nanotechnology, in general, is the technology used for making stuff smaller. It has been developed rapidly and is applied in several fields - such as healthcare, military, and so on. In healthcare, for example, a tiny pill with camera attached is used for the purpose of identifying diseases and health issues deep inside human body. In military, nanotechnology is used in creating nano drones and invisible combat suits. They, as scientists believe, are going to make advantage effects on warfare. https://www.youtube.com/watch?v=J-lvsIMtEVo https://www.youtube.com/watch?v=7xEuOVjhWbs
