The synthesis of a silver-PMMA nanocomposite film includes mixing an aqueous extract of-(also known asand fenugreek) seeds with an aqueous solution of silver nitrate, thereby reducing the silver ions to silver metal nanoparticles. A solution of the silver nanoparticles is added to a solution of PMMA [poly (methyl methacrylate)] in N'N-dimethylformamide (DMF) with stirring at 90&#xb0; C. A light 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.

Synthesis of silver-PMMA nanocomposite film

The synthesis of a silver-PMMA nanocomposite film using herbal extract includes mixing an aqueous extract ofbuds with an aqueous solution of silver nitrate, thereby reducing the silver ions to silver metal nanoparticles. 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&#xb0; 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 againstandshowed zones of inhibition, also suggesting use as an antimicrobial or antibacterial agent.
