Biocompatibility of Biodegradable Polymer Films Based on Poly(lactic-co-glycolic acid) of Various Molecular Weights

摘要

Various poly(lactic- co -glycolic acid)-based polymeric films with various molecular weights were obtained. The mechanical characteristics of these films were investigated. It was shown that the obtained polymer films do not have a short-term toxic effect on mammalian cells. The percentage of actively dividing cells on such polymer films is 1.5–3.0 times higher than when grown on culture glass, and, accordingly, the cell layer is formed faster. The obtained poly(lactic- co -glycolic acid)-based polymer films are biocompatible.
