Published: Feb. 22, 2025

Abstract The development of multifunctional nanotheranostic platforms with stimuli‐responsive capabilities holds significant potential for enhancing cancer diagnosis and treatment. Herein, a glutathione (GSH)‐responsive semiconducting polymer (SP) system, SP/DOX‐SS‐PEG nanoparticles (NPs), is presented, designed combined near‐infrared II (NIR‐II) fluorescence imaging (FI) chemo‐photothermal therapy. amphiphilic SP (SP‐SS‐PEG) synthesized through multi‐step reaction sequence, including Suzuki coupling, amidation, thiol‐disulfide exchange reactions, subsequently encapsulates the anticancer drug doxorubicin (DOX) self‐assembly, resulting in formation GSH‐responsive NPs. These NPs exhibit high photothermal stability GSH‐triggered DOX release. In vitro studies demonstrate that display enhanced cellular uptake robust cytotoxicity against 4T1 cells under 808 nm laser irradiation. Upon intravenous injection tumor‐bearing mice, NIR‐II FI reveals efficient tumor accumulation prolonged retention vivo anti‐tumor efficacy indicate irradiation achieve most inhibition growth, minimal systemic toxicity. Taken together, these findings highlight promising as platform precision theranostics, integrating imaging, release, dual
