Biocompatible materials

Individual silk protein molecules, or “silk fibroins” (blue), are deposited on a graphene surface surrounded by water (green and red spheres) and grow into an atomically precise two-dimensional (2D) sheet. Controlled deposition of silk fibers could lead to numerous biodegradable electronic devices.

Tiny Implantable Microphone Could Revolutionize Cochlear Implants

MIT engineers developed a metal-free, Jell-O-like material that is as soft and tough as biological tissue and can conduct electricity similarly to conventional metals. The new material, which is a type of high-performance conducting polymer hydrogel, may one day replace metals in the electrodes of medical devices. Credits:Image: Felice Frankel
