Injectable DNA medibots
It's not quite Fantastic Voyage, but researchers at the Weizmann Institute of Science in Israel have demonstrated an injectable DNA-based biocomputer that can diagnose and treat certain kinds of cancer. If the computer detects the genetic signature of cancer, it releases a bit of DNA "known to interfere with the cancer cell�s activities, causing it to self-destruct," according to a press release issued by the Institute.

The world�s smallest computer (around a trillion can fit in a drop of water) might one day go on record again as the tiniest medical kit. Made entirely of biological molecules, this computer was successfully programmed to identify � in a test tube � changes in the balance of molecules in the body that indicate the presence of certain cancers, to diagnose the type of cancer, and to react by producing a drug molecule to fight the cancer cells.
