Summary: Developing safe and high-quality theranostic agents for cancer treatment is crucial. In this study, the clinical indocyanine green (ICG) was coupled with biocompatible poly(styrene-alt-maleic anhydride) (PSMAn) to obtain PSMAn-ICG polymer. The self-assembly of its hydrolyzed product in water resulted in ICG-conjugated poly(styrene-alt-maleic acid) nanoparticles (PSMA-ICG NPs). These NPs demonstrated good solubility and stability in aqueous solutions, high photostability, and reduced damage to red blood cells, highlighting the importance of PSMA coupling. Furthermore, the PSMA-ICG NPs showed significant tumor targeting and long-term imaging capabilities, as well as potent photothermal therapy when combined with near-infrared laser irradiation. Overall, this study provides promising phototheranostic agents for clinical applications.
