Surface functionalization and antibacterial activity of biomedical textiles with metal oxides-carbon nanocomposites

Abstract

Carbon nanostructures were synthesized from honey by hydrothermal method. The synthesized nanocarbon structures were treated with synthesized Fe2O3 and TiO2 nanoparticles to form nanocomposites (NC). The synthesized nonaoparticles and their composites with carbon nanostructures were validated by XRD, FTIR, SEM and TEM for their morphology and microstructures. XRD analysis revealed the crystallographic structure of Fe2O3, TiO2 and the amorphous nature of carbon nanostructures . A rod like structure for Fe2O3 and TiO2, and nano sheet like structure for carbon was observed by TEM. The NC was impregnated onto fabrics and the presence of the NC on to the fabrics was confirmed by Laser Raman, FTIR and EDAX. The antibacterial effects of NC impregnated fabrics were evaluated against gram positive and gram negative bacteria by agar diffusion plate test. The NC fabrics showed a clear zone of inhibition, indicating good antibacterial activity against both bacterial strains. The washing test revealed durability of the coated fabrics.
