The characterization of a polyelectrolyte complex material comprised of two biopolymers, a chitosan upper layer and a gellan gum under layer, is reported. It is shown that the upper layer of chitosan with incorporated levofloxacin displays an antibacterial activity, while the under layer of a gellan gum/TiO(2) composite supports the growth of fibroblastic cells.
报告了一种由两种生物聚合物组成的聚电解质复合物材料的特性，该材料的上层为壳聚糖，下层为结冷胶。结果表明，掺入左氧氟沙星的壳聚糖上层具有抗菌活性，而下层的结冷胶/TiO(2)复合材料则支持成纤维细胞的生长。
