Synthesis and Stabilization of Ag Nanoparticles on a Polyamide (nylon 6,6) Surface and its Antibacterial Effects

Silver nanoparticles (NPs) were synthesized by controlled reduction of Ag+ ions with sodium borohydride at room temperature. Nylon 6,6 was loaded with Ag nanoparticles by entrapment of Ag+ ions into the polymer network, followed by reduction. The nanocomposite was characterized by scanning microelectronic microscopy (SEM). In vitro antibacterial tests were performed using Escherichia coli (E. coli) to determine the antibacterial capability of the Ag/nylon nanocomposite.
