In this week's issue of Nature, a research team reports creating the first drug-delivery microchip, the progenitor of devices that may be capable of releasing variable doses of multiple drugs over an extended time once swallowed or implanted under the skin. The new chips have yet to be tested in animals or humans, but already some experts believe they have the potential to radically change the way many patients take medication, such as those with Parkinson's disease or cancer, where doctors need to adjust medications and dosages.
