NIR-II-Activated iridium single-atom nanozymes for synergistic antibacterial therapy and tissue regeneration in MRSA-infected wounds and acute lung injury

Bioactive Materials
Methicillin-resistant Staphylococcus aureus (MRSA) remains a major pathogen in ventilator-associated pneumonia and wound infections. To address the limitations of traditional antibiotics, we developed a novel iridium-based single-atom catalyst (Ir/CN SAC)

Acid‐Responsive Nanobot‐Integrated Core‐Shell Microneedles Reprogram the Degenerative Annulus Fibrosus Microenvironment Through Epigenetic Suppression of Ferroptosis

Advanced Science, EarlyView.
An acid‐responsive core‐shell microneedle system normalizes the degenerative annulus fibrosus microenvironment by consuming pathological H+, generating O2, and providing NIR‐amplified redox buffering. Mechanistically, it epigenetically suppresses ferroptosis via DNMT3A‐dependent methylation of the ATF3 promoter, relieving ATF3‐mediated repression of ...

A lattice oxygen-free design for efficient and stable photothermal methane dry reforming

Nature Communications
Photothermal dry reforming of methane, a promising approach to producing syngas, typically uses oxide materials and is mediated by lattice oxygen. However, it is limited by the balance of the oxygen-releasing/replenishing loop. Here, we present a methane

Asymmetric Structure‐Driven Functional Synergy: A Multistimuli‐Activated Janus Nanomotor for Self‐Amplifying NO Cascade Therapy

Advanced Science, EarlyView.
The Janus nanomotors leverage an “asymmetric structure‐driven functional synergy” strategy to orchestrate spatiotemporally coordinated catalytic functions, in situ self‐amplifying NO generation, and deep tumor penetration, thereby enabling controllable, sustained, and uniform NO generation within the tumor microenvironment.
