Is the emerging field of nanomedicine a breathtaking technological revolution that promises remarkable new ways of diagnosing and treating diseases?

Scientists have confirmed the feasibility of using a new drug delivery system — the basis for a battery-powered skin patch — to administer medication that shows promise for treating peripheral artery disease (PAD) and healing stubborn skin ulcers and burns.

Scientists are reporting the development and successful initial testing of a new form of methotrexate — the mainstay anticancer drug — designed to be given as nose drops rather than injected.

U.S. scientists have developed an unusual nano-centered drug delivery system in which the drug itself acts as the delivery vehicle. The process of efficiently delivering drugs, especially those that are hydrophobic, or water-repellant, to tumors or other disease sites has long been problematic.
