Dual‐Targeting Biomimetic Nanozymes Loaded Microneedle Patch Promotes Scarless Wound Healing Through Anti‐Inflammatory and Anti‐Fibrotic Effects

Advanced Science, EarlyView.
This study developed a dual‐targeting biomimetic nanozyme hybrid system (Cu‐CeO2@ABs‐FTP) and integrated it with HAMA hydrogel to fabricate a microneedle patch (CAF@MN). The patch promotes fibroblast‐mediated wound repair, targets macrophages to induce M2 polarization, and targets myofibroblasts to exert anti‐fibrotic effects, thereby enabling rapid ...

Responsive Membrane Antenna Enables Adaptive Biohybrid Interface for Photosynthesis Promotion, Stress Reporting and Modulation

Advanced Science, EarlyView.
An environmentally responsive antenna assembled onto the algal cell membrane creates a biohybrid with a responsive interface that promotes photosynthesis under normal conditions and shifts to H2O2‐triggered stress reporting and modulation upon stress onset, boosting environmental sensing and adaptive response.

Operando X-ray Fluorescence Analysis of Through-plane Cerium Ion Radical Quencher Migration in Polymer Electrolyte Fuel Cells

Electrochemistry
Polymer electrolyte fuel cells (PEFCs) need to achieve long-term durability for widespread commercialization. Chemical degradation of the perfluorosulfonic acid (PFSA) membrane caused by radical species (·OH) can be mitigated by adding cerium ions as ...

An Injectable ROS‐Responsive Nanozyme Hydrogel Regulates the Uterine Microenvironment to Prevent Intrauterine Adhesions

Advanced Science, EarlyView.
The injectable CeTA@GPP hydrogel is administered via intrauterine injection, forming a protective barrier. In the high ROS inflammatory microenvironment of injured endometrium, boronate ester cleavage triggers responsive CeTA release and local enrichment.

D4F‐Functionalized Ceria Nanozyme‐CasRx Platform Suppresses STING and Reprograms the Renal Immune Niche in Acute Kidney Injury

Advanced Science, EarlyView.
D4F‐functionalized ceria nanozyme–CasRx nanoparticles preferentially target renal macrophages through SR‐B1‐mediated uptake in ischemia–reperfusion injury. Ceria scavenges excessive ROS, while CasRx silences STING signaling, shifting macrophages toward a less inflammatory, pro‐resolving state and increasing the proportion of regulatory T cells.

Syngas Production via CO₂ Reforming of Methane over SrNiO₃ and CeNiO₃ Perovskites

Energies, 2021
The development of a transition-metal-based catalyst with concomitant high activity and stability due to its distinguishing characteristics, yielding an abundance of active sites, is considered to be the bottleneck for the dry reforming of methane (DRM).

Beyond Biomimetics: Pathology‐Informed Engineering Rescues Reconstituted HDL From Inflammatory Dysfunction for Sepsis Immunotherapy

Advanced Science, EarlyView.
A pathology‐informed engineering strategy rescues reconstituted HDL from inflammatory dysfunction in sepsis. By integrating a ceria nanozyme‐celastrol coordination complex, the platform preserves HDL structure and endotoxin handling, sustains hierarchical intracellular delivery, and enhances immunoregulation across pathological models, translating ...
