Journal Article 2024 03 01 We consider of the antimicrobial activity on the Ag nanoparticles(Ag NPs) aqueous solutions, which was prepared using a stabilizer, such as poly(N vinyl 2 pyrrolidone PVP , for Staphylococcus aureus) S aureus and Escherichia coli E coli by measuring the minimum inhibitory concentration MIC . Antimicrobial effect of Ag NPs for S aureus and E coli was investigated using disk diffusion method Also, the Ag NPs did show the antimicrobial activity for the test organisms Antibacterial activity of Ag NPs was found to be dependent on the shape of bacteries.
