Abstract

The titanium dioxide (TiO2) and zinc oxide (ZnO) nanomaterials are widely used for several biomedical applications because of their semiconductor property. The present study demonstrates a strategy for synthesis of zinc oxide nanorod (ZnONR) doped titanium dioxide nanosheets (ZnONR@TiONS) via hydrothermal method. A series of characterization techniques indicated that TiONS exhibited band gap energy of 3.09 eV, while the ZnONR@TiONS showed 2.83 eV. XPS analysis confirmed the 4+ oxidation state of TiONS and 2+ oxidation state of ZnONR. In vitro cytotoxicity test indicated that the ZnONR@TiONS showed 99% of cell viability without any toxicity under 50 μg/mL of concentrations.
