细菌纤维素生物医学材料的现状及展望

摘要

细菌纤维素是由细菌合成的纯净纳米纤维素构成的网状纤维,具有优良的形态学、生物学、物理学性能以 及合成可控性,因此在生物医学材料领域被广泛应用.介绍了近年来细菌纤维素应用于敷料、人造皮肤、组织修复材料和膳食纤维等方面的研究进展,并对其生物降解能力、生物相容性和纤维定向等性能的提高作出了展望.%Bacterial cellulose is composed of a pure cellulose nanofiber mesh spun by bacteria. The excellent properties on morphology, biology, physics and synthetic controllability make it a natural choice for application in biomedical devices field. Introducing the research progress for which bacterial cellulose is currently being used as surgical dressing, artificial skin,repair materials of tissue engineering and dietary supplements. In addition,the improvement of properties on biodegradability,biocompatibility and fiber orientation is forecasted.
