Hydrogel silver nanocomposites have shown immense potential in many biomedical applications, specifically wound healing. The combination of bi‐metallic (Ag, Au) hydrogel nanocomposites are developed to enhance their antimicrobial activity. This paper presents the fabrication of bi‐metallic nanocomposites obtained from the synthesis of acrylamide (AM) and 2‐acrylamido‐2‐methyl‐1‐propanesulfonic acid (AMPS) based hydrogels for antimicrobial applications. The nanocomposite formation was confirmed by scanning electron microscopy (SEM), thermal analysis (TGA/DSC), as well as X‐ray diffraction (XRD) methods. The bi‐metallic nanocomposite hydrogel has shown significant antibacterial activity on bacillus. Therefore, these bi‐metallic antibacterial materials are promising candidates for a wide range of biomedical applications. © 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
