Ejecta‐Modulated Bubble Dynamics Play a Dominant Role in Stone Retropulsion
Stone motion during laser ablation is shown to result primarily from asymmetric cavitation bubble collapse, not from ejecta recoil. This challenges long‐standing assumptions and highlights the dominant role of bubble dynamics in laser–material interactions.

A developmentally inspired osteochondral construct integrates mechanical and metabolic dual gradients within a 3D‐printed platform. Human MSC spheroids are spatially directed to form cartilage–bone interfaces, enabling evaluation of regeneration without biochemical reagents and assessment of drug responses. This physiologically relevant, phase‐specific

A multifunctional injectable microsphere system is fabricated via UV‐assisted microfluidic cross‐linking, integrating nanozyme‐based ROS scavenging, sustained dexamethasone release, and stem cell delivery. Upon IA injection, the microspheres adapt to joint stress, suppress inflammation, and promote cartilage regeneration, offering a minimally invasive ...

A NETs‐inspired Ti3C2/LDH hydrogel integrates trapping, ROS boosting, and M2‐immunomodulation for MRSA‐infected wound repair. ABSTRACT MRSA infections give rise to chronic cutaneous and advance into profound tissue invasions, including osteomyelitis and sepsis—conditions for which existing clinical interventions offer only limited efficacy. The utility

Boosting Photo‐Pyroelectric Effect via Tunable Polarization and Interfacial Defect Engineering
This study reports Ba(Ti0.85Zr0.15)O3 nanocatalysts with enhanced polarization and oxygen‐vacancy‐rich interfaces for efficient NIR‐II photo‐pyroelectric therapy. Zr doping boosts the pyroelectric coefficient and accelerates polarization switching, while oxygen vacancies improve photothermal conversion and surface reactivity.

Engineering MnPt Bimetallic Nanozymes for Cascade Enzymatic Therapy and Enhanced Radio‐Immunotherapy
A CD44‐targeted MnPt bimetallic nanozyme (HD@MnO2) integrates multienzyme‐like activity with cGAS–STING activation to boost radio‐immunotherapy. Through cascade biocatalysis, it depletes glutathione, relieves hypoxia, and amplifies ROS, enhancing radiotherapy‐induced DNA damage and immunogenic cell death. The nanozyme promotes dendritic cell maturation

To address multidrug‐resistant urinary tract infections (MDR‐UTIs), we developed Cu‐ZIF8‐Ru nanozyme featuring an asymmetric Cu─N─Ru catalytic site. This unique structure enhances multienzyme‐mimetic activity, eradicating resistant bacteria by inducing a cuproptosis‐like death pathway through intracellular Cu2+ accumulation and energy depletion.

We studied how five common immunosuppressants behave when delivered directly to a transplant site instead of systemically. Using a vascularized implant for islet transplantation, we show that local delivery protects grafts, limits drug spread to the rest of the body, and produces distinct immune signatures.
