Аntimicrobial activity of oxidized cotton fabric impregnated with Cu-based nanoparticles

Abstract

This study discusses the antimicrobial activity of cotton (CO) fabric oxidized with NaIO4/NaClO2 prior to in situ synthesis of Cu-based nanoparticles (NPs). Carboxyl groups generated by oxidation of cellulose were utilized for efficient binding of Cu2+-ions from the solution of CuSO4 which were further reduced by extract of Arctostaphylos uva-ursi (L.) Spreng., Ericaceae (bearberry leaves) as a green reducing agent. A number of free carboxyl groups was highly affected by the initial concentration of NaIO4 solution. Color yield of impregnated fabrics varied with amounts of synthesized Cu-based NPs. Fabricated samples provided excellent antibacterial activity and controlled release of Cu2+-ions.
