Biodegradable Transistors
Abstract:
Fully biodegradable organic transistors, recently fabricated by researchers at Stanford University, could be used to control temporary medical implants placed in the body during surgery.
Biodegradable electronics "open up opportunities for implants in the body," especially if the electronics prove inexpensive, says Robert Langer, institute professor at MIT, who was not involved with the research. Implants might incorporate the organic electronics with biodegradable drug-delivering polymers. Doctors might implant such a device during surgery, then activate it from outside the body with radio frequencies to release antibiotics if needed during recovery. The electronics could also help monitor the healing process from inside the body. After healing is complete, the entire device would dissolve in the body.
