Accurate intraoperative tumor delineation is critical to achieving successful surgical outcomes. However, conventional techniques typically suffer from poor specificity and low sensitivity are time-consuming, which greatly affects decision-making. Here, we report a cascade activatable near-infrared fluorescent (NIRF) probe IR780SS@CaP that can sequentially respond acidity elevated glutathione levels for accurate localization.

Revealing changes in the tumor microenvironment is crucial for understanding cancer and developing sensitive methods precise imaging diagnosis. Intracellular hydrogen peroxide (H2O2) microenvironmental factors (e.g., viscosity polarity) are closely linked to various physiological pathological processes, making them potential biomarkers cancer. However, a triple-response theranostic probe therapy has not yet been achieved due lack of effective tools. Herein, we present mitochondria-targeting near-infrared (NIR) fluorescent probe, VPH-5DF, capable simultaneously monitoring H2O2, viscosity, polarity through dual NIR channels. The specifically detects H2O2 via emission (λem = 650 nm) shows high sensitivity viscosity/polarity deep channel ≈ 750 nm). Furthermore, only monitors mitochondrial polarity, fluctuations endogenous/exogenous levels but also distinguishes cells from normal multiple parameters. Additionally, VPH-5DF can be employed monitor alterations levels, as well during drug-induced pyroptosis living cells. After treatment with chemotherapy-induced oxidative damage mitochondria activated pathway, leading robust antitumor response, evidenced xenograft models. Thus, this prodrug offers new platform vivo diagnosis anticancer chemotherapy.

Improving the retention of small-molecule-based therapeutic agents in tumors is crucial to achieve precise diagnosis and effective therapy cancer. Herein, we propose a β-galactosidase (β-Gal)-activated red light-induced RNA modification (GALIRM) strategy for prolonged tumor imaging. A β-Gal-activatable near-infrared (NIR) fluorescence (FL) positron emission tomography (PET) bimodal probe 68Ga-NOTA-FCG consists triaaza triacetic acid chelator NOTA 68Ga-labeling, β-Gal-activated photosensitizer CyGal, singlet oxygen (1O2)-susceptible furan group modification. Studies have demonstrated that emits an activated NIR FL signal upon cleavage by endogenous β-Gal overexpressed lysosomes, which combined with PET imaging 68Ga allowing highly sensitive ovarian Moreover, capability generating 1O2 under 690 nm illumination could be simultaneously unlocked, can trigger covalent cross-linking between nucleotides cytoplasmic RNAs. The formation probe-RNA conjugate effectively prevent exocytosis prolong tumors. We thus believe this GALIRM may provide entirely new insights into long-term efficient treatment.
