Graphene Oxide Synthesized Using Mild Reduction Method Improved the Anti-Tumor Efficacy on Human Cervical Cancer

Abstract

In the current study, graphene oxide (GO) as raw material synthesized using different reduction degrees prepared by a mild method. We used Fourier transform infrared spectroscopy (FTIR), Raman Spectroscopy (Raman), X-ray photoelectron spectroscopy (XPS), ultraviolet-visible spectroscopy (UV-Vis), transmission electron microscopy (TEM) and EDS spectroscopy to characterize its structure and morphology. The results of cell experiments showed the significant cytotoxicity activity of reduced GO under laser irradiation. In addition, reduced GO kills tumor cells through the dual effects of photothermal and phototoxicity under near-infrared (NIR) laser irradiation and can be used as photothermal therapy
