Nanotechnology is a new upcoming technology which focuses on the technology at a nanometer scale. It is becoming more and more popular due to the fact that more than 9 billion is invested in it each year and it has great potential in the medical community. A nano-meter is 1*10^-9 meters, and to put it into perspective a germ is about 1000 nanometers wide. Nanotechnology involves developing and designing at a level that is not visible to the human eye. Nanotechnology is on the same level as atoms which means that with increases in this field, designers will be able to the smallest anatomical changes. Even the smallest anatomical differences can change the physical make-up of an element. By changing the chemical design of carbon atoms,engineers are able to make carbon nanotubes which are lighter than normal carbon atoms, and also stronger. Carbon nanotubes are used to design racing bicycles because of their lighter weight, the cyclist can use more energy to go faster.
Carbon nanotubes can also be redesigned to create nanofibers. These can be used in the medical field as good materials for bandaging wounds, artificial organ transplants, and tissue engineering. Nanofibers are very useful, but the biggest challenge that engineers have had to overcome, is the preciseness that each nanofiber must be. The use of nanoparticles of certain metals, has been found to create more uniform nanofibers that can be used. A new study has find that nanofibers can be made out of proteins and that these nanofibers are easily accepted by the body. These protein nanofibers are have been found to have the capabilities of targeting certain problem areas of the body, and releasing medications at those areas. The researchers at Polytechnic Institute of New York University plan to study this aspect more to see if it could be a possible solution for cancer.
The rise of nanotechnology is creating many new medical advances. The approximate size of a virus is 100 nm, and with nano technology, these viruses can be altered. Nanotechnology has been called the “sub-microscopic lab bench,” because it allows researchers to directly change the make-up of a material. It is especially useful in manipulating DNA. There are many diseases that are the result of a abnormality in the DNA strand. These people can undergo DNA therapy to lessen the impact of that abnormality, and DNA therapy heavily focuses on nanotechnology.
