biodegradable polymer

biodegradable polymer

A material which degrades primarily by the action of microbial enzymes, which has applications in medical devices for orthopaedics, dentistry, drug release (e.g., stents) and tissue engineering. To be termed biodegradable, the rate of degradation must take place in a specified time period comparable to existing natural biodegradable materials or processes.
