Abstract
MnO2 nanoparticles (NPs) and magnetic Fe3O4 NPs are excellent support material for silver NPs due to their exceptional physical and chemical properties. The Ag–MnO2 and Ag–Fe3O4 nanomaterials are superior for antibacterial application compared to pristine Ag NPs because of their characteristic features such as high stability, nontoxicity, easy synthesis by eco-friendly method, biocompatibility, high surface area, easy separation, and reusability. Strong interactions occur between Ag NPs with MnO2 and Fe3O4 NPs, due to which Ag NPs are stabilized over MnO2 and Fe3O4 NPs and also decrease the toxicity of free Ag NPs to human cells. Due to higher dispersion of Ag NPs over support materials (MnO2 and Fe3O4), interactions with microbial cells becomes easy and lower concentration of Ag NPs is needed for higher antibacterial activity. Ag NPs immobilized on Fe3O4 NPs can be easily separated by magnetic separation and can be reused.
