Abstract
Biogenic silver nanoparticles (AgNPs) obtained using metal-reducing bacteria Shewanella oneidensis MR-1 and silver-nitrate salts are included in liquid and dry formulations in the composition of such polymeric materials as acrylic paint, epoxy glue, and chelate compounds of copper and zinc with different types of ligands. The preservation of a high level of biocidal activity of AgNPs in the composition of nanocomposite materials in relation to microorganisms of various systematic groups is shown. It is established that the contribution of biogenic AgNPs to the activity level of biocidal metal chelates is 20–25%. For the first time, an assessment of the antimicrobial properties of the original polymer materials is carried out and the different sensitivity of strains to their effects is revealed, which indicates the need to take into account strain specificity when selecting components of a biocidal nanocomposite material.
