Engineers from the University of Nebraska-Lincoln, Harvard and MIT are trying to come up with a bandage that is capable of dose-dependent drug release with different drug release profile. The study was published in a paper in the journal Advanced Functional Materials.

The dressing is made of composite fibers with a core electrical heater covered by a layer of a hydrogel containing thermoresponsive drug carriers. It is not just a regular bandage that protects the injury from exposure but also has a stamp-sized microcontroller which sends a voltage through certain of the fibers, warming them and activating the medications lying dormant in the hydrogel. The medications could be anything from topical anesthetics to antibiotics to more sophisticated things like growth hormones.

In addition to further testing to satisfy the FDA, the researchers are also investigating how to integrate sensors with the fibers, to measure blood glucose levels, pH and other indicators of how the healing process is going. Soon the bandage may even include a progress bar...
