Abstract

We report the dependency of Cu doping on the structure, morphology, magnetic properties and the regulation of cytotoxicity and biocompatibility in macrophages (RAW 264.7) of ZnO nanostructures. A viable chemical bath deposition technique has been explored for the synthesis of undoped and Cu-doped ZnO nanostructures, using the precursor's mixture of Zinc nitrate hexahydrate, Hexamethylenetetramine and Copper (II) acetate monohydrate. The structural and morphological studies confirms the incorporation of Cu 2+ ion into ZnO matrix hinders the nanorod growth and the nanorod morphology disappears at higher doping. Cu ions substitute Zn 2+ sites in its divalent state as confirmed from X-ray photoelectron spectroscopy studies. Magnetic measurement ensures a dramatic change in the magnetic features due to doping, which is directly reflected in the temperature- and field-dependent magnetization curves. From the cytotoxicity assessment with RAW 264.7 macrophage cell lines, the Cu doped ZnO samples are non-toxic. Our study exhibits the potential usefulness of the materials in spintronic/ magnetic media device applications as well as Cu doping as a promising approach for new functional biomaterials for bio-medical applications.
