However, their clinical translation is hindered by high systemic toxicity, suboptimal therapeutic efficacy, and compromised chemodynamic performance caused by tumor antioxidant defense mechanisms. A multifunctional therapeutic platform (Ru-PC-PEITC-ALG) was developed through the coordination-driven self-assembly of ruthenium ions with procyanidins (PCs) to form Ru-PC nanoparticles, followed by coencapsulation with phenethyl isothiocyanate (PEITC) in a sodium alginate hydrogel. The Ru-PC complex demonstrated exceptional photothermal conversion efficiency, enabling rapid intratumoral temperature elevation under 808 nm laser irradiation to achieve localized thermal ablation. Simultaneously, Ru-PC exhibited tumor microenvironment-responsive catalytic activity, catalyzing the conversion of hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) into highly toxic hydroxyl radicals (·OH) via Fenton-like reactions. This ROS generation was substantially amplified through synergistic photothermal acceleration of reaction kinetics and PEITC-mediated glutathione (GSH) depletion, which effectively disabled the antioxidant defense system. Systematic evaluations, including in vitro cytotoxicity assays, transcriptomic sequencing, and murine xenograft models, confirmed the platform's superior tumor suppression ability and favorable biosafety profile.

This study introduces a novel approach utilizing mannose-modified microbubbles (MB<sub>man</sub>) targeting CD206 (mannose receptor) positive M2 macrophages for early CR detection.

However, this difference is not observed in isograft rats at any of the indicated time points. These findings suggest an increase in M2 macrophage infiltration in allografts compared to isografts.

This study presents a machine-learning-driven framework that integrates microrheological features into diffusional fingerprinting to characterize nano- and micro-scale particle diffusion patterns in mucus and assess the effect of mucus microrheology on such movements. We investigated the diffusion of fluorescent-labeled polystyrene particles in native pig mucus and two artificial mucus models. Particles (100, 200, and 1000 nm in diameter) with carboxylate- or amine-modified surfaces were tracked during passive diffusion. From each particle trajectory, 20 features -including microrheology-based parameters- were extracted. Based on these features, seven supervised machine learning models were applied to classify or identify similarities among mucus hydrogels. Of these, gradient boosting achieved the highest accuracy. SHapley Additive exPlanations analysis identified creep compliance as the most influential feature in distinguishing the mucus models. In native mucus, smaller negatively charged nanoparticles exhibited the highest mobility, with fewer particles being in the immobile and subdiffusive states. Microrheology data further indicated that larger particles experienced greater restriction owing to the elastic properties of native mucus. In contrast, smaller particles interacted more with the viscous liquid phase. A comprehensive feature-wide analysis revealed that hydroxyethyl cellulose (HEC)-based artificial mucus more closely resembled native pig mucus than the polyacrylic acid-based model. In conclusion, the machine-learning-driven fingerprinting approach, incorporating microrheological features, successfully differentiated the microstructural characteristics and rheological properties of the three mucus models.
