Application of nanotechnology to medicine

Nanotechnology refers to situations where at least one dimension of interest is around or is less than 100 nm. This is of significance in life sciences where many fundamental sub-cellular and protein functions take place at this spatial scale. The ability to image and manipulate biological moieties at this scale opens up many new possibilities. Further, some of the most exciting applications of nanotechnology are where a particular geometrical size, right size, may promote or inhibit a particular behavior. In this paper a quick overview of some new discoveries will be made. The remainder will focus on drug delivery, tissue engineering, and biosensors.
