Glutathione and viscosity double-locked response fluorescent probe for imaging and surgical navigation of hepatocellular carcinoma†

Abstract

Early diagnosis and precise treatment of hepatocellular carcinoma (HCC) are crucial for human health. Therefore, addressing the potential markers of HCC, glutathione (GSH) and viscosity, we constructed a fluorescent probe (PG-V) activated cascadically by GSH/viscosity. PG-V possessed excellent photophysical properties and biocompatibility, and could specifically illuminate tumor tissue, achieving fluorescence imaging of HCC, and imaging-guided tumor resection.
