PVP-coated Sb₂Se₃ nanorods as nanotheranostic agents for photoacoustic imaging and photothermal therapy in NIR-I bio-windows.

ABSTRACT: Antimony selenide (Sb₂Se₃) as a simple, low toxicity, low-cost p-type semiconductor material with broad absorbance ranging from the UV to the NIR region has many potential applications in photovoltaic, thermoelectric, and phase-change memory devices. Owing to these excellent properties, Sb₂Se₃ nanorods were firstly synthesized with triphenylantimony and dibenzyldiselenide under solvothermal conditions. In order to enhance the biocompatibility of the Sb₂Se₃ nanorods, polyvinylpyrrolidone (PVP) was coated onto the surface of the Sb₂Se₃ nanorods to form PVP-coated Sb₂Se₃ nanorods. The cell viability of PVP-coated Sb₂Se₃ nanorods toward Hep-2 cells was assessed fo
