It has been found for a long time that chitosan (CS) and silver nanoparticles (AgNPs) have outstanding antibacterial activities but there have been some drawbacks restricting a popular usage as such. Consequently, in this research, CS modified was combined with AgNPs with the purpose of expanding applications and enhancing the antibacterial activities. | Synthesis and antibacterial activity of composite based on chitosan grafted (N-butyl acrylate) and silver nanoparticles
