Silver nanoparticles (Ag NPs) have attracted much attention because their powerful antimicrobial activity. Furthermore, as compared to bacteria, Ag NPs are less hazardous to human cells. As a result, Ag NPs-based compounds have been applied widely in a variety of consumer goods ranging from household appliances, medical equipment, dental materials to water treatment. Herein, we try to improve the antimicrobial activity of Ag NPs by utilizing polymer hydrogel as a matrix for embedding Ag NPs. To this end, we combined sodium alginate and 2-aminoethyl methacrylate in the presence of EDC and NHS to form sodium alginate with a methacrylate group. Subsequently, we mixed methacrylated-alginate with Ag NPs and photoinitiator, then exposed it to the UV light to embed the NPs inside the hydrogel. Next, we investigated the antimicrobial properties of the resultant hydrogel composites as a function of Ag NPs concentration. |
