Ferroptosis, an iron- and reactive oxygen species (ROS)-dependent cell death, holds significant promise for tumor therapy due to its ability induce lipid peroxidation (LPO) trigger antitumor immune responses. However, elevated cholesterol levels in cancer cells impede ferroptosis compromise function. Here, a novel nanozyme, Fe-MOF/CP, composed of iron metal-organic framework (Fe-MOF) nanoparticles loaded with oxidase PEGylation integrated immunotherapy is introduced. Fe-MOF/CP depletes generates hydrogen peroxide, enhancing ROS inducing LPO, thereby promoting ferroptosis. This process disrupts raft integrity downregulates glutathione peroxidase 4 suppressor protein 1, further facilitating Concurrently, augments immunogenic reduces programmed death-ligand 1 expression, revitalizes exhausted CD8

Chemodynamic therapy (CDT) offers an effective in situ activation for cancer treatments. However, the efficiency of CDT is limited by antioxidant system within tumor cells, including antioxidative niacinamide adenine dinucleotide phosphate (NADPH) and glutathione (GSH). Zeolitic imidazolate framework-8 (ZIF-8) widely used therapies due to its tunable structure properties, but ZIF-8 itself lacks application. In order meet application demand CDT, we select Cu2+ ions that can catalyze a Fenton-like reaction 2-nitroimidazole (2-NI) consume NADPH as new inorganic–organic connection components. Based on reasonable coordination mode ZIF-8, nanoplatform with adjustable size constructed. The synthesized Cu-NI NPs are triple responsive hypoxia, GSH, hydrogen peroxide (H2O2), which selectively enhance Cu+/Cu2+-mediated induce apoptosis/ferroptosis. This work will promote diversification structures provide good implications realization enhanced CDT.

Hypoxia can lead to liver fibrosis and severely limits the efficacy of photodynamic therapy (PDT). Herein, carbon nitride (CN)-based hybrid nanoparticles (NPs) VPSGCNs@TSI for light-driven water splitting were utilized solve this problem. CNs doped with selenide glucose (Se-glu) enhance their red/NIR region absorption. Then, vitamin A-poly(ethylene glycol) (VA-PEG) fragments aggregation-induced emission (AIE) photosensitizers TSI introduced into Se-glu-doped CN NPs (VPSGCNs) construct NPs. The introduction VA-PEG enhanced targeting activated hepatic stellate cells (HSCs) reduced toxicity ordinary cells. VPSGCN units could trigger generate O2 under 660 nm laser irradiation, improve hypoxic environment site, downregulate HIF-1α expression, activate HSC ferroptosis via HIF-1α/SLC7A11 pathway. In addition, generated also increase reactive oxygen species (ROS) production in a environment, thereby completely reversing hypoxia-triggered PDT resistance effect. combination water-splitting materials showed 1 + > 2 effect increasing levels fibrosis, promoting HSCs caused by hypoxia.

Photodynamic therapy (PDT) has been employed as a noninvasive treatment option for bladder cancer due to its controllability and minimal toxicity. However, the efficacy of PDT is often compromised by hypoxic microenvironment solid tumors. To address this challenge, our research dedicated developing Ru-Se-Ce6 nanoreactor that combines photoresponsiveness Ru-Se coordination bonds reactive oxygen species (ROS) triggered diselenide bonds, achieving dual-controlled release photosensitizer enhance effectiveness. The photoresponsive catalytic characteristics were validated through synchrotron radiation density functional theory calculations. Under laser irradiation, metal-to-ligand charge transfer (MLCT) within ruthenium complex leads cleavage bond, resulting in liberation complex, which significantly improves O2 generation from H2O2 tumor (TME). In vivo assessments demonstrated disrupted mitochondrial membrane potential via excessive ROS production, leading cell cycle arrest apoptosis. Additionally, revealed significant suppression subcutaneous orthotopic models while exhibiting good biocompatibility. These findings propose potent innovative approach therapy.

Abstract The rapid healing of infected wounds holds immense significance for patients suffering from persistent inflammation, which could lead to disability or even mortality if left unaddressed. However, current therapeutic modalities face formidable challenges in effectively addressing the complex pathogenesis chronic wounds. Herein, a robust strategy is reported combine synergistic photodynamic and piezocatalytic therapies through piezo‐phototronic effect efficient wound healing. approach capitalizes on flexible organic/inorganic piezoelectric film composed poly(vinylidene fluoride‐trifluoroethylene) (P(VDF‐TrFE)) zinc oxide (ZnO) nanorods as substrate. Additionally, tetraphenylporphyrin (TPP), photosensitizer, integrated into P(VDF‐TrFE)/ZnO framework create composite film, P(VDF‐TrFE)/ZnO/TPP. This generates both field reactive oxygen species (ROS) upon mechanical deformation, built‐in further enhances ROS production by photosensitizers light exposure. Both vivo vitro experiments demonstrate that significantly accelerated with combined illumination stimulation, showcasing profound work not only elucidates mechanisms underlying these coupled but also introduces an practical method treating routine outdoor activities under sunlight.
