Burkova, I. Beleneva, Yu. Shchipunov] Optimal conditions have been determined for the synthesis of silver nanoparticles via reduction of Ag+ cations with sodium borohydride in the presence of a polysaccharide, sodium alginate, as a stabilizer. The optical properties of nanoparticles have been characterized with the use of absorption spectroscopy in UV and visible regions, while their shapes, sizes, and crystallinity have been studied by transmission electron microscopy. Cross linking of alginate macromolecules with calcium cations has been used to obtain hydrogels and, then, films containing silver nanoparticles. The films thus prepared have exhibited a high bactericidal activity with respect to a number of model pathogenic microorganisms, including gram-negative and gram-positive bacteria and yeast.
