Antibacterial Activity of Chemogenic Copper Nanoparticles Coated Cotton Fabrics against Pyogenic Bacteria Isolated from Post Operative Patients

Abstract

In this present study, copper nanoparticles coated on the cotton fabrics was evaluated for the antibacterial property against bacterial strains isolated from post operative patients.In this study, CUNPs synthesized by chemical reduction method and the synthesized nanoparticles characterized by UV spectroscopy, energy dispersive X ray spectroscopy and further characterized for its size by SEM. CUNPs coated on the bleached cotton fabrics by pad dry cure method. Coating of CUNPs to cotton fabric conferred by SEM and FTIR. The coated fabrics were examined in the range of basic physical–mechanical parameters such as the tensile strength, the bursting strength and air permeability.Anti bacterial activity was determined against the clinical isolate of Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa by agar diffusion assay. Copper nanoparticles synthesized by chemical reduction was primarly confirmed by the colour change of the reaction mixture from blue to olive green, plasmon absorption maxima at 600 nm and uniform sp
