SnS nanosheets for efficient photothermal therapy

A novel photothermal agent based on PEGylated SnS nanosheets is developed via a simple solvothermal route and the subsequent exfoliation is carried out using an ultrasonication method. The PEGylated SnS nanosheets exhibit much higher extinction coefficient and photothermal conversion efficiency than bulk SnS. With the irradiation of the NIR light, cancer cells in vitro can be efficiently killed by the photothermal effects of the SnS nanosheets. The findings reported here show promising potential for further exploration of 2D nanomaterials as a nanoplatform for cancer therapy.
