Improving drug delivery with nanotechnology

About 99% of medicinal molecules don't reach their targets and subsequently stay in the body of patients. Some of these molecules can be very toxic—particularly in the case of those designed to target cancers. Consequently, research is being undertaken to find more effective ways of safely transporting and delivering drugs. This is where medical nanotechnology may be able to help.

Researchers are hoping to create a device which can carry a drug payload to its target, be monitored throughout its journey, and deliver—and all without being attacked and destroyed by the body's natural defences. This calls for a rather complex system and, among other things, possesses stealth design characteristics. Such a schema is described in this video:
