Comparative Study of Antibacterial Activity of Bacterial Cellulose/AgNPs Composites Prepared by Different Methods

摘要

Bacterial cellulose (BC) is a type of nanoscale cellulose produced by microorganisms.In this work,BC films were utilized as a template to in siru synthesize silver nanopartides (AgNPs) by a variety of simple chemical strategies,induding chemical reduction with NaBH4 or vitamin C,hydrothermal treatment and UV radiation.A comparative study of the formation of AgNPs such as the silver particle size and silver content,as well as the antibacterial activity of the BC-AgNPs nanocomposites by different preparation methods and reaction conditions was investigated.A benefidal support was provided for future applications of AgNPs contained BC composites with antibacterial properties.
