Synthesis of stable silver nanoparticles using aqueous solutions of pullulan and its polyaldehydes
Abstract
Pullulan is one of the extracellular polysaccharides produced by the "black yeast" Aureobasidium pullulans that is widely spread in different ecological sites, including forest, soil and peat. Silver nanoparticles have been synthesized using pullulan and its polyaldehydes that served to cross-link the individual polymeric chains of this polysaccharide and 100 nM AgNO3. Obtained solutions of polymers were used as both the reducing and stabilizing agents. Reactions were carried out in two different conditions in the microwave and in the autoclave. The morphology of the Samples was analyzed using scanning electron microscopy. Antimicrobial activity testing was carried out at agar plates with different concentrations of the investigated solutions, against various strains of bacteria and fungi.
