| Sumario: | Galina F Prozorova,1 Alexsandr S Pozdnyakov,1 Nadezhda P Kuznetsova,1 Svetlana A Korzhova,1 Artem I Emel'yanov,1 Tamara G Ermakova,1 Tat'yana V Fadeeva,2 Larisa M Sosedova31AE Favorsky Irkutsk Institute of Chemistry, Siberian Branch, Russian Academy of Sciences, Irkutsk, 2Scientific Center of Reconstructive and Restorative Surgery Siberian Branch of Russian Academy of Medicinal Sciences, Irkutsk, 3Institute of Occupational Health and Human Ecology, Siberian Branch of Russian Academy of Medicinal Sciences, Angarsk, RussiaAbstract: New water-soluble nontoxic nanocomposites of nanosized silver particles in a polymer matrix were synthesized by a green chemistry method. Nontoxic poly(1-vinyl-1,2,4-triazole) was used as a stabilizing precursor agent in aqueous medium. Glucose and dimethyl sulfoxide were used as the silver ion-reducing agents to yield silver nanoparticles 2–26 nm and 2–8 nm in size, respectively. The nanocomposites were characterized by transmission electron microscopy, ultraviolet-visible and Fourier transform infrared spectroscopy, X-ray diffraction, atomic absorption, and thermogravimetric data analysis. The nanocomposites showed strong antimicrobial activity against Gram-negative and Gram-positive bacteria.Keywords: silver nanoparticles, poly(1-vinyl-1,2,4-triazole), glucose, dimethyl sulfoxide, green synthesis |
