(Pohang, Korea), were used in the experiment(Table 1) These silver nanoparticles are classified in different manufacturing processes. Silver nanoparticles were brought at an initial concentration of 1,000 ppm and different working concentrations of silver nanoparticles(i e., 10 ppm, 25 ppm, 50 ppm, and 100 ppm) were prepared by diluting the original stock solution with distilled water. All AgNP solutions were stored at 4°C until further use.
