Researchers develop flexible, biocompatible polymers — with optical abilities

Researchers have discovered how to transfer the optical properties of silicon crystal sensors to plastic, an achievement that could lead to the development of flexible, implantable devices capable of monitoring the delivery of drugs within the body, the strains on a weak joint or even the healing of a suture. The discovery is detailed in the March 28 issue of Science by a team that pioneered the development of a number of novel optical sensors from silicon wafers, the raw starting material for computer chips.
