With the rise of nanotechnology, inorganic nanomaterials have been developed, which have a marked microbicidal effect on a wide variety of microorganisms, such as viruses, bacteria and fungi. In this thesis, the synthesis, characterization and study of the antimicrobial activity of copper and oxide nanoparticles obtained by chemical route was carried out. To obtain copper oxide nanoparticles was used as a precursor copper sulphate pentahydrate and glucose, ascorbic acid and hydrazine were used as organic reducers. The characterization was carried out by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The in vitro antimicrobial activity of the copper oxide nanoparticles on the Staphylococcus Aureus bacterium was also determined, determining the minimum inhibitory concentration (CIM). The results of the analysis by X-ray diffraction, confirmed that from the synthesis using ascorbic acid as a reducer 100% pure Cu was obtained with particle sizes in the micrometer range. The copper particles show quite faceted crystals of polyhedral shape. The synthesis using glucose as a reducer results in the obtaining of 100% Cuprite (Cu2O) with variable morphology, spheres, cubes and tetrahedra were observed, very dependent on the concentration of NaOH used in each synthesis, with particle sizes in the nanometric and micrometric ranges, that is, nanoparticles and nanostructures of Cu2O were obtained. The synthesis using hydrazine as a reducer resulted in the formation of nanostructures 74% Cu2O and 26% Cu, that is, do not get 100% cuprite. According to the results of the antimicrobial activity, it can be concluded that copper oxide, cuprite Cu2O, has an antimicrobial effect on Staphylococcus aureus bacteria. The CIM corresponds to a concentration of 16 mg / mL.
