Abstract

The present invention is directed to a novel poly (diol citrates)-based nanocomposite materials created using completely biodegradable and biocompatible polymers that may be used in tissue engineering. More specifically, the specification describes methods and compositions for making and using nanocomposites comprised of citric acid copolymers and polymers including but not limited to poly(L-lactic acid) (PLLA) and poly(lactic-co-glycolic acid) (PLGA).
