A new electronic implant can fight bacterial infection inside the body and then harmlessly dissolve. The simple, passive device is made entirely of silk and magnesium, which are both benign, biocompatible materials. The device, which can be loaded with antibiotics, could be implanted inside the body during surgery and then wirelessly triggered from outside to kill bacteria using heat or by releasing drugs. Once its work is done, it would dissolve.
