Uses Poly(D,L-lactide), Resomer R203s is a copolymer of 1,4-Dioxane-2,5-dione (D485883) and DL-Lactide (L113518). Because the copolymer is biocompatible and biodegradable it is used for controlled release of drugs and therapeutic agents.
Uses Controlled release
Uses Poly(D,L-lactide-co-glycolide) is a synthetic amino acid that has been used to deliver macromolecular therapeutics.
