The effect of silver and zinc nanoparticles on the structural characteristics of bacterial cells

Abstract

The paper presents the results of studying the influence of nanoparticles of silver and zinc on the culture of Madin-Darby Bovine Kidney (MDBK) and bacterial cells of E. coli at various dilution rates and various incubation times. The interaction of MDBK cells with the nanoparticles of zinc has a strong deleterious effect on the cells and causes morphological changes in them. At the same time, no toxic effects were observed after the interaction of silver nanoparticles and the cells. During incubation of E. coli bacterial cells with zinc nanoparticles, not only changes in the morphology of the cell membrane surface but also the destruction of bacterial cells were observed. During incubation with silver nanoparticles at various dilution rates for various times, changes in the cell shape from rod-shaped to rounded, without symptoms of destruction were noted.
