GREENER SYNTHESIS OF CUO NANOCRYSTALS USING RAMBUTAN NEPHELIUM LAPPACEUM L. PEEL EXTRACT AND ITS ANTIBACTERIAL APPLICATIONS
AbstractGreen synthesis of copper oxide nanocrystals was carried out via hydroxide precipitation using rambutan peel wastes. The successful formation of copper oxide nanocrystals was confirmed by X-Ray diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) and Atomic Force Microscopy (AFM) analysis. XRD analysis confirms the calculated average crystallite size of higher intense plane peak (111) was 35.74 nm. SEM and TEM show the surface morphology and look flake-shaped. The AFM analysis shows needle formation of CuO nanoparticles. A possible mechanism for the formation of CuO nanocrystals with rambutan peel extract was also proposed. The prepared nanocrystals were coated on the cotton fabric, and their antibacterial activity was analyzed. Both CuO and CuO nanocrystals coated cotton fabric showed good antibacterial activity towards Escherichia coli E. coli and Staphylococcus aureus S. aureus. Wash durability test was carried out on the test fabrics showed that the significant antimicrobial activity was actively retained in the fabrics treated with CuO nanocrystals.
