Abstract:
In this study, silver nanoparticles (AgNPs) were synthesized by using Malva sylvestris flower extract. Different parameters such as, pH, extract volume, silver nitrate concentration, temperature and reaction time were controlled correctly and the effect of them on the synthesis of nanoparticles were investigated. Some of techniques like, UV-Vis, FTIR, SEM, TEM, and XRD were used to analyze the characteristics of AgNPs. According to our results, the shape and size of nanoparticles were spherical and about ۲۰ - ۳۰ nm range, respectively. In addition, the surface plasmon resonance (SPR) of nanoparticles occurred in ۴۴۵ nm. The effect of catalytic activity AgNPs synthesized on the reaction Sodium Borohydride (NaBH۴) with Methylene Blue (MB) and its antibacterial activity on (Escherichia coli, Staphylococcus aureus, Bacillus subtilis and Salmonellatyphy murium) as a references bacteria have been studied. Also, the effect of Malva sylvestris flower extract on them was measured and analyzed precisely. The results showed ability of catalytic activity on the reduction of MB. Further, synthesized nanoparticles have significant ability antibacterial activity against gram negative bacteria (Escherichia coli and salmonella typhy murium).
