In this work, an environmental benign, sugarcane juice (SCJ) was applied as an eco-friendly stabilizing agent to synthesize copper oxide nanoparticles (CuO NPs). To produce CuO NPs, 2, 5 and 10 ml of juice were added during the synthesis. The produced CuO NPs were characterized using FTIR, which confirmed the transformation of functional groups through Cu-O. The XRD analysis confirmed the monoclinic crystalline structure and purity of the material. SEM images confirm the nanoparticles formation. Quantitative estimation of Cu, O and C present in samples were carried out by EDS. Square, rectangular, cubic cylindrical and spherical shaped particles observed from the TEM micrographs. Furthermore, Micro-raman and X-ray photoelectron spectroscopy (XPS) were taken to assure the formation of CuO NPs. The results revealed that the SCJ is a good stabilizing agent which reduces the size of particles significantly at higher concentrations and altered shapes to spherical. Hence, it sugarcane juice could be applied as a green stabilizing agent to fabricate the CuO NPs. Antibacterial activity of CuO NPs was assessed against some pathogenic bacteria.
