ALDH Inhibition‐Primed Photocatalysis Disrupts Cancer Stemness Plasticity

Angewandte Chemie, EarlyView.
DE‐Et converts ALDH‐mediated redox buffering into a photoredox vulnerability by coupling ALDH inhibition with red‐light‐driven catalytic NADH oxidation. This enzyme‐coupled photoredox strategy sustains mitochondrial NADH/NAD+ imbalance, induces pyroptotic tumor cell death, suppresses tumor growth in vivo, and promotes systemic antitumor immunity ...

MOF‐Derived Cu‐TiO2/Alginate Micromotors for Buoyancy‐Regulated 3D Motion

Advanced Science, EarlyView.
In this work, cyanobacteria‐inspired sodium alginate (SA)/Cu‐TiO2/Fe3O4 hydrogel micromotors generate and encapsulate O2 microvesicles upon light irradiation, enabling buoyancy‐mediated Z‐axis upward migration and surface enrichment at the light‐exposed water‐air surface.

Modulating Covalent Organic Framework Nanochannel Microenvironments for Sustainable Hydrogen Peroxide Photosynthesis

Angewandte Chemie, EarlyView.
Alkoxy side chains regulate hydrazone‐linked COF nanochannel microenvironments by tuning pore polarity, reactant adsorption, and charge‐separation behavior. The optimized framework facilitates oxygen activation and hydrogen peroxide photosynthesis in real water and a 1 L natural‐sunlight reactor. LCA further shows that natural sunlight and larger‐scale

Integrated O2 and H2 Gas Therapy via Microneedle‐Assisted Photocatalytic Water Splitting for Accelerating Diabetic Full‐Thickness Skin Wound Healing

Advanced Science, EarlyView.
A concept of integrated O2 and H2 gas therapy is achieved using a gas‐producing material. PMP nanoparticles, fabricated from platinum, MIL‐101(Fe)‐NH2, and phosphotungstic acid, are integrated into bilayer gelatin methacryloyl microneedles for transdermal delivery. These microneedles enable integrated O2 and H2 gas therapy and promote wound healing via

Unlocking Li/Mg‐Based Photochemical Nitration Platforms for Anticancer Drug Discovery

Advanced Science, EarlyView.
Two low‐toxicity light main‐group metal photochemical systems based on lithium and magnesium are constructed for selective C(sp2)‐H (di)nitration of anilines. The obtained dinitrated products exhibit anti‐HCC (hepatocellular carcinoma) and anti‐KYSE30 cell activities, holding promise as novel antitumor candidates.

Surface‐Engineered Ti3C2Tx MXene/Cu2O Photocathodes for Highly Selective Photoelectrocatalytic CO2 Reduction to Ethanol

Advanced Energy Materials, EarlyView.
Surface‐engineering Ti3C2Tx MXenes with an in situ‐grown TiO2 layer on the surface in combination with visible‐light‐absorbing Cu2O significantly enhances charge separation and carrier extraction while improving Cu2O resistance to photocorrosion. The resulting Cu2O/TiO2‐MXene photocathodes enable highly selective, solar‐driven ethanol production ...

Boosting Membrane Interactions and Antimicrobial Effects of Photocatalytic Titanium Dioxide Nanoparticles by Peptide Coating.

Small
Photocatalytic nanoparticles offer antimicrobial effects under illumination due to the formation of reactive oxygen species (ROS), capable of degrading bacterial membranes. ROS may, however, also degrade human cell membranes and trigger toxicity.
