Enhanced antimicrobial and anticancer properties of ZnO and TiO2 nanocomposites.

The study describes the antibacterial and anticancer activities of a nanocomposite prepared by mixing zinc oxide and titanium dioxide nanoparticles. The particle mixtures were analyzed by X-ray diffraction, Field emission scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, and dynamic light scattering techniques. Thus, analyzed samples were subject to disc diffusion method at various concentrations to analyze their antibacterial activities against two Gram-positive and two Gram-negative bacteria. The same samples were then analyzed for their anticancer activities on four different cell lines. The results indicate a synergistic effect of the nanocomposite on both antibacterial and anticancer properties when compared to their individual counterparts.
