SYNTHESIS OF BACTERIAL CELLULOSE AND SILVER NANOPARTICLES COMPOSITE AND INVESTIGATE ITS ANTIBACTERIAL ACTIVITY

Abstract

Composite of bacterial cellulose and silver nanoparticles (BC/AgNPs) that synthesized by in situ method is aimed to produce an antibacterial material. Reducing agents Natri Borohydrua (NaBH4) and Ethylene Glycol (EG) were used to synthesis composite by directly reducing ion Ag⁺ to silver nanoparticles that integrated to cellulose fibers. The composites were then investigated for their bactericidal performance to two Gram negative bacteria (E. coli and P. aeruginosa) and two Gram positive bacteria (S. aureus and S. epidermidis). The results of this study demonstrated that both composites synthesized by NaBH₄ and EG could eliminate all 4 bacteria strains. The composite BC/AgNPs has potential application for wound treatment and prevention from bacterial infection.
