Nanoparticles improve delivery of medicines and diagnostics

Tiny, biodegradable particles filled with medicine may also contain answers to some of the biggest human health problems, including cancer and tuberculosis. The secret is the size of the package. Using an innovative technique they invented, a Princeton University-led research team has created particles that can deliver medicine deep into the lungs or infiltrate cancer cells while leaving normal ones alone. Only 100 to 300 nanometers wide -- more than 100 times thinner than a human hair -- the particles can be loaded with medicines or imaging agents, like gold and magnetite, that will enhance the detection capabilities of CT scans and MRIs....
