Controlled and targeted drug delivery represents one of the frontier areas of science. Drugs can be encapsulated in a variety of carriers. The carrier can be a carbon nanotube, a nanotube made of something other than carbon, a structure like a silicon wafer with antibodies or some other molecule that will bind to the drug. Nanoparticles can enter damaged cells and release enzymes that initiate the cells auto destruct sequence, known as ├ó┬?┬?apoptosis├ó┬?┬Ł. Alternatively they can release enzymes to try to repair the cell and return it to normal functioning. Drugs in nanocrystalline form can be administered in smaller doses because they can be delivered directly to the tissue and in controlled doses related to the patient├ó┬?┬?s requirements. Reduction of particle size and increased surface area, enhancing solubility, increasing oral bioavailability, targeting of tissues, cells are some of the special properties when using nanoparticles. An overview of the role of nanotechnology for drug delivery applications is presented here.
