Cu/Dioxidine hybrid composites:
cryochemical synthesis and antibacterial activity
Abstract
Hybrid nanocomposites consisting of
antibacterial drug dioxidine and copper nanoparticles were obtained by means of
cryochemical synthesis. UV spectroscopy, x-ray diffraction, PAM and
low-temperature adsorption of argon showed the formation of drug substances
particles with the size of 100‑500 nm in which copper particles with the
size of 50‑150 nm are incorporated. The resulting composites possessed
higher antibacterial activity against E. coli 52 than initial dioxidine
and copper nanoparticles.
Key words: copper nanoparticles, dioxidine,
cryochemical synthesis, hybrid materials, nanocomposites, antibacterial
activity.
