Investigation of the antibacterial activity of the nanostructured system of copper sulfate in Na-carboxymethyl cellulose on the example of an indigenous strain of the gram-negative bacterium Esherichia coli

Abstract

The article provides a study of the antibacterial activity of nanostructured copper sulfate in Nacarboxymethyl cellulose on the example of an indigenous strain of the gram-negative bacterium Esherichia coli by the disk-diffusion method. The study revealed that the modification of the active material increases its biocidal properties by 321.34; 121.5; 369.5; 562.6 and 351.7% with an increase in the weight ratio “core : shell” to 1:2 and concentration from 0.5 to 1% in aqueous suspensions.
