[Study on the biocompatibility and toxicology of biomaterials--poly(epsilon-caprolactone)].

Four observation indexes were selected to evaluate the biocompatibility and toxicology of biodegradable materials poly(epsilon-caprolactone)(PCL), which is synthesized in our laboratory using Ti(OBu)4 as an initiator. The results showed that PCL films had a mild inflammatory reaction in the early days of planting and after 3 months the inflammation basically disappeared. We conclude that PCL material possesses good biocompatibility and has a good developmental prospect.
