Methods for the synthesis of nanoparticles (NPs) of zinc oxide in an aqueous-alcohol medium are described. Using scanning electron microscopy (SEM), it is shown that NPs with a size of 5–49 nm are formed. Optimal conditions for the treatment of cellulose materials with aqueous solutions of zinc-oxide NPs are developed. SEM studies confirm the presence of zinc-oxide NPs on the surface of cellulose materials, which are rather unevenly distributed. Antimicrobial activity is assessed by the degree of inhibition of bacterial growth ( Escherichia coli ) on materials treated with zinc-oxide NPs compared to the control samples. Cellulose materials modified with zinc oxide NPs are shown to have antibacterial activity against bacteria and molds.
