•Low molecular COS was successfully used for COS/silver nanocomposites synthesis.•The method is facile, economic and environmentally benign.•The synthesized nanocomposites were extremely stable for more than 2 months.•The COS/silver nanocomposites exhibited stronger antibacterial activity than COS.
In this study, we demonstrate a facile approach to prepare chitosan oligosaccharide (COS)/silver nanocomposites by use of vitamin C and low molecular COS as reducing agent and capping agent. Morphology and crystalline structure of the COS/silver nanocomposites were characterized. The possible biochemical mechanism leading to the formation of the nanocomposites was investigated by FTIR. The synthesized COS/silver nanocomposites exhibited stronger antibacterial activity than the COS.
