Description
Summary:The aim of this study was to develop antimicrobial nanocomposite textile material comprising of Cu-based nanostructures synthesized on oxidized cotton fabric using Arctostaphylos uva-ursi (L.) Spreng., Ericaceae (bearberry leaves) as a green reducing agent for adsorbed Cu 2+ -ions. In order to provide sufficient number of carboxyl groups for complexation with Cu 2+ -ions a two-step oxidation process with NaIO 4 and NaClO 2 was carried out. The influence of NaIO 4 concentration on content of carboxyl groups and Cu-based nanoparticles was studied by FTIR and AAS. HPLC analysis identified the gallic acid known as a reducing agent in bearberry leaves extract. FESEM and XRD analyses revealed that using bearberry leaves extract and gallic acid solution as reducing agents led to a formation of spherical Cu 2 O/CuO nanoparticles and CuO nanosheets, respectively. These nanoparticles and nanosheets provided excellent antibacterial activity against Gram-negative bacteria Escherichia coli and Gram-positive bacteria Staphylococcus aureus. Cytotoxicity on human keratinocyte cells was shown to depend on their copper content.
