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

Nanotechnology and Medicine- Melissa Schwartz Nanotechnology allows us to build tools smaller than a human cell. These tools have high accuracy and can provide great advances in the medical field. Some applications could include identifying and killing cancer cells, providing oxygen, and could be used as artificial mitochondria. http://www.zyvex.com/nanotech/nanotechAndMedicine.html
Nanotechnology in Livestock Feeds – Julia Wiemeyer Cereal grains used to feed livestock in the meat production industry must often be stored for extended periods of time due to seasonal harvests. Because of this the cereal grains accumulate aflatoxins, which are very dangerous for animals. However, using nanotechnology the Food and Agriculture Organization has developed a nanocomposite of MgO-SiO2 to absorb the aflatoxins present in order to make the food safe for animal consumption. - http://www.pagepress.org/journals/index.php/nd/article/viewFile/nd.2012.e4/pdf
Rocking Out With Carbon Nanotubes - Thao Hua Carbon nanotubes have outstanding thermal and electrical conductivity, which translates to a highly efficient thermoacoustic effect. When a current runs through the nanotube, nearby air is heated; by controlling the current, a sound wave is produced. A yarn-like array design is used to dissipate the heat more efficiently from the nanotubes and is tested by Tsinghua researchers to play a whole year with no significant sign of wear. Making it more durable than conventional speakers. http://cen.acs.org/articles/91/web/2013/09/Rocking-Carbon-Nanotubes.html
Nanotechnology in Medicine: Drug Delivery to Specific Cells – Gisselle Alvarado There is currently research for the development of nanoparticles that will be able to deliver drugs, heat, light, or other substances to target specific cells such as cancer cells. They want to deliver chemotherapy drugs directly to the cancer cells so they do not damage the healthy cells. This development may also help with an earlier detection of cancer. http://www.understandingnano.com/medicine.html
I included information regarding how heart health can be improved by carbon nanotube technology.
Nanotechnology in X Ray Technology Around late 2009 clinical tests started in order to test a new type of x-ray machine which would use carbon nanotubes in order to increase the efficacy of the x-rays. The benefits of using carbon nanotubes included being able to image organs that are perpetually in motion such as the heart and lungs. The way it works is by replacing the conventional tungsten filament (x-ray machines usually only have one)with an array of carbon nanotubes which would emit the electrons that would normally be done by the tungsten filament. Replacing the tungsten filament with hundreds (if not more) carbon nanotubes allows for increased resolution of the x-ray images taken. The carbon nanotubes allow for a faster exposure which prevents the blurring of moving organs. The University of North Carolina was still in the process of researching this type of imaging. Here's the link to the article in case anyone wants to follow up: https://www.technologyreview.com/s/414584/nanotube-powered-x-rays/
Israel has created this insect sized killing machine, called the Bionic Hornet. This is a drone which looks like and is the size of a hornet is capable of navigating through narrow alleyways to target otherwise unreachable enemies such as rocket launchers. It is one of several weapons being developed by scientists to combat militants. Other nanotechnology weapons include super gloves that would give the user the strength of a "bionic man" and miniature sensors to detect suicide bombers. http://www.spiegel.de/international/bionic-hornets-israel-looks-at-the-next-generation-of-warfare-a-449171.html
The disease-targeting "nanorobot" - Matt Morales Researchers at the University of Florida have programmed newly created "nanorobots" to shut down the genetic production of disease-related proteins that cause diseases such as cancer and hepatitis C. These nano-particles only target and enter diseased cells while leaving healthy cells untouched. For example, the University of Florida researchers created a particle to target the virus for hepatitis C, sneakily enter the target cells, and prevent copies of the hepatitis C virus from being made. http://www.understandingnano.com/nanozyme-viral-infections.html
Bionic Plants -- Jesisca Oei Plants have multiple functions, from providing food, fuel and oxygen that we breathe to adding beauty to the Mother Nature. Recently, a team of MIT researchers have developed a technique by using nanomaterials to enhance plant's functionality, such as monitoring environmental pollutants. They have reported that by implanting carbon nanotubes into the chloroplast, where photosynthesis take place, it has boosted the plant's ability to capture light energy by 30 percent. They have also used another type of carbon nanotube to modify plants to have the ability to detect gas nitric oxide. http://news.mit.edu/2014/bionic-plants
Nanotechnology in Food Packaging and Food Safety - Abd Hamid, Ammar Hafiz This research focuses on the application of nano-materials such as polymer/clay nano-composites as a high barrier packaging material, silver nano-particles as potent antimicrobial agent, nanosensors and nanomaterial-based assays for the detection of food-relevant analytes. http://www.sciencedirect.com/science/article/pii/S0021979711008642
Bionic Plants - Jesisca Oei Plants function in many ways: providing food and fuel, releasing oxygen, and adding beauty to the Mother Nature. A team of MIT researchers plan to develop a new technique using the nanomaterials to enhance plants' already multi-functional features, such as their energy production and a new function, that is the ability to monitor environmental pollutants. They have reported that by implanting carbon nanotubes in the chloroplast, where photosynthesis takes place, plants can capture light energy by 30 percent. They have also modified plants to be able to detect nitric oxide by using another type of carbon nanotube. The nanobionic plant was first implemented as a project to build self-repairing solar cells modeled on plant cells. The next step of this was to develop the photosynthesis function of chloroplasts isolated from plants into solar cells. http://news.mit.edu/2014/bionic-plants
