A solution of the silver nanoparticles is added to a solution of PMMA [poly (methyl methacrylate)] in N′N-dimethylformamide (DMF) with stirring at 80° C. A brown solution of silver colloids develops, which is cast in a glass plate and the DMF is evaporated at room temperature, leaving a silver-PMMA nanocomposite film. Testing on water shows the silver-PMMA nanocomposite film prevents or inhibits growth of microbes, suggesting use as an antimicrobial or antibacterial agent, e.g., in water purification. In addition, testing by disc diffusion against E. coli and Bacillus cereus showed zones of inhibition, also suggesting use as an antimicrobial or antibacterial agent.
