New nanoparticles for targeting tumors

As a wide variety of nanoparticles continue to demonstrate their ability to improve the delivery of imaging agents and drugs to tumors, nanoparticle researchers have turned their attention to the challenge of systematically determining how a given nanoparticle’s physical and chemical characteristics affect its ability to target tumors. Such data could provide drug developers with guidelines to help them select the most effective type of nanoparticle for a given therapeutic or imaging application.
