synthesis, characterization and antimicrobial properties of cuo nanoparticles against gram-positive and gram-negative bacterial strains

Nano structured materials have wide range of applications due to their interesting size-dependent chemical and physical properties compared to particles of size in the range of micrometer. copper oxide nano materials are of interest on account of their potential uses in many technological fields. in this study cuo nanoparticles were synthesized via simple sol gel method using basic cuso4 as wet chemically synthesized precursor and naoh as stabilizing agent .samples were characterized by x-ray diffraction(xrd),infrared spectrum (ir),and scanning electron microscope(sem).we studied the antibacterial activity of this cuo nanoparticles against gram-positive and gram-negative bacterial strains. using this method, cuo nanoparticles could be synthesized without using organic solvent, expensive raw materials and complicated equipments. besides simplicity, the advantage of producing nanoparticles by this method is that it is easeful, flexible, fast, cost effective, and pollution free.
