Silver nanoparticles were loaded to hydrogel systems through in situ reduction of silver nitrate in the presence of sodium borohydride as a reducing agent. The synthesized hydrogels and their composites were characterized using FTIR, scanning electron microscopy, EDX, and EDX-mapping. The antimicrobial activity of hydrogel-silver composite was determined using well agar and broth dilution tests. In the first stage, four different hydrogel-silver composites were evaluated against six different microorganisms using the well agar technique. The most effective hydrogel-silver composite among all tested was poly(AAm-co-VI-co-AMPS)-Ag, while the most sensitive and resistant microorganisms among all tested were Staphylococcus cerevisiae and S. aureus, respectively. Poly(AAm-co-VI-co-AMPS)-Ag composite was used in modeling the inhibition kinetic of Escherichia coli. The present study displays that hydrogel-silver composite has considerable antimicrobial activity, which deserves further investigation for use in clinic application and industrial processing.
