عنوان انگلیسی Microwave Irradiation in Green Antimicrobial Silver Nanoparticles Synthesis using Arabic Gum: Preparation, Optimization and Characterization
چکیده انگلیسی مقاله Silver nanoparticles (Ag NPs) as a new antibiotic generation were green produced using Arabic gum, as capping and stabilizing agents, under microwave heating. Results indicated that using 0.5 mL of 3 mM silver nitrate solution and 0.5 mL of Arabic gum solution (1 % W/V), and microwave heating time of 150 s, Ag NPs were fabricated minimum broad emission peak (λmax) and maximum concentration of 424±2 nm and 25±2 ppm, respectively. Transmission electron microscopy and dynamic light scattering analyses specified that the fabricated spherical Ag NPs using these optimal synthetic parameters had particle size, polydispersity index and zeta potential values of the 89 nm, 0.238 and +50 mV. Furthermore, antibacterial test indicated that diameters of the formed clear zones around the holes having Ag NPs were 13 and 15 mm, toward Escherichia coli and Staphilococcus aurous, respectively. Antifungal assessment also shown that synthesized Ag NPs could strongly inhibit the growth of Aspergillus flavus mycelia in the plate during incubation for 7 days. Synthesized Ag NPs using the obtained optimum conditions can be widely used in the food, pharmaceutical and cosmetics areas, due to those high antimicrobial activities.
