Green synthesis of ZnO-TiO₂/RGO nanocomposites usingSenna surattensisextract: a novel approach for enhanced anticancer efficacy and biocompatibility

Abstract

The aim of the present study is to enhance the anticancer and biocompatibility performance of TiO2 and ZnO nanoparticles, and, ZnO-TiO2 and ZnO-TiO2/reduced graphene oxide nanocomposites, against two types of human cancer (HCT116) and normal (HUVCE) cells.

Origin of the Improved Photoelectrochemical and Photocatalytic Activity in a ZnO-TiO2 Nanohybrid Revealed by Experimental and Density Functional Theory Studies

“…The peak located near 2350 cm –1 is assigned to the adsorbed water in the samples. The FTIR spectrum of ZnO-TiO 2 exhibits the overlap of the fingerprint regions of both ZnO and TiO 2 , confirming the formation of a nanohybrid . No additional peaks are found in the FTIR spectrum, which indicates that the prepared samples are free of impurities.…”

“…The FTIR spectrum of ZnO-TiO 2 exhibits the overlap of the fingerprint regions of both ZnO and TiO 2 , confirming the formation of a nanohybrid. 67 No additional peaks are found in the FTIR spectrum, which indicates that the prepared samples are free of impurities. The Raman results shown in Figure 3b indicated that the ZnO-TiO 2 heterojunction could preserve the crystallinity and the vibrational properties of TiO 2 NPs even after the formation of the heterojunction.…”
