Abstract
Sodium alginate (SA) and bacterial cellulose (BC) are widely used in many applications such as scaffolds and wound dressings due to its biocompatibility. Silver sulfadiazine (AgSD) is a topical antibacterial agents used as a topical cream on burns. In the study, novel BC/SA-AgSD composites were prepared and characterized by SEM, FTIR and TG analyses. These results indicate AgSD successfully impregnated into BC/SA matrix. The swelling behaviors in different pH were studied and the results showed pH-responsive swelling behaviors. The antibacterial performances of BC/SA-AgSD composites were evaluated with Escherichia coli, Staphylococcus aureus and Candida albicans. Moreover, the cytotoxicity of BC/SA-AgSD composites was performed on HEK 293 cells. The experimental results showed BC/SA-AgSD composites have excellent antibacterial activities and good biocompatibility, thus confirming its utility as potential wound dressings.
