is needed that could target tumor cells - nanoparticles provide such a potential vehicle. Nanoparticles can loosely be defined as synthetic structures with dimensions ranging from 1-100 nanometers (a nanometer is one-billionth of a meter, about the size of a water molecule), whose unique properties, at least in part, depend on their physical size and component chemistry. Many contain a hollow core into which a wide range of cargo can be packaged. Dr. Federman will develop and test …
