Antimicrobial activity of CuFe2O4 nanoparticles obtained by electric explosion of Fe and Cu wires

Abstract

Nanoparticles with a spinel structure were obtained by the method of electric explosion of Fe and Cu wires in an oxygen-containing atmosphere. Their characteristics and antimicrobial activity were investigated depending on the energy input into dispersible conductors. As the input energy increases, the specific surface area of the samples obtained increases, which indicates the formation of smaller particles. XRD analysis shows CuFe2O4 phase. Studies have been conducted on the antimicrobial activity of samples using the broth dilution method. It was shown that the obtained copper ferrite nanoparticles with respect to the bacterial strains of E.coli and MRSA have antibacterial effects in varying degrees. Nanoparticles with a large specific surface area have the highest antibacterial activity.
