Novel Strategy

A novel strategy toward one-pot hydrothermal synthesis of copper sulfide nanoplates-decorated reduced graphene oxide (RGO–CuS) composites was developed. CuS nanoplates were successfully loaded onto the surface of RGO in the hydrothermal procedure, which was confirmed by transmission electron microscopy, UV-Vis–NIR and Raman spectroscopy. The as-synthesized RGO–CuS composites showed pronounced enhanced optical absorbance in near infrared (NR) region and higher photothermal conversion efficiency than noncomposite GO and CuS nanoplates. The RGO–CuS materials were used in photothermal ablation of cancer cells with a 980[Formula: see text]nm laser irradiation and showed improved performance than CuS nanoplates.

Viability of cancer cell is an important indicator of physiological state and function of cells, which can be effected by the change of pH in the medium solution, due to the increase of carbon oxide and lactic acid caused by respiration. Although many methods have been developed to detect the viability of cells, mostly based on cytochemical staining and polymerase chain reaction (PCR) technology are time consuming. In this paper, an electronic device was made by thermal reduced graphene oxide (RGO) for detection of cancer cell viability in real-time. This electronic device could be used to monitor the metabolic activity and viability of cancer cells based on the change in pH value. As the pH decreases, colon cancer cells loose viability and the current decreases. This RGO device is simple, sensitive and label-free and could serve as a platform for detection of cells and drug testing.
