Radical‐Mediated, Substrate‐Independent Fabrication of Hybrid Solid–Hydrogel Materials With Tunable Crosslinking: An Initiator‐ and Crosslinker‐Free Approach

Advanced Science, EarlyView.
This work introduces a substrate‐independent, reagent‐free plasma strategy that forms radical‐rich interlayers for covalent hydrogel attachment without initiators or crosslinkers. The long‐lived radicals drive in situ gelation, creating robust, cytocompatible hybrid solid–hydrogel constructs across diverse substrates.

Asymmetric Active Center Triggers Side‐On Photo‐Fenton‐Like Reaction Through Polar Charge Transfer and Self‐Adapting Sulfur Vacancies

Advanced Science, EarlyView.
The Cu‐Zn3In2S6 photocatalyst (Cu‐ZISV) with asymmetric Cu‐SV‐Zn sites was designed and synthesized to boost peroxymonosulfate (PMS) activation kinetics. The side‐on photo‐Fenton‐like reaction by the asymmetric Cu‐SV‐Zn site accelerated PMS activation and pollutant degradation, and the first‐order kinetic constant of Cu‐ZISV increased by 4.87 times ...

Iron Oxide Nanozyme as Reactive Oxygen and Nitrogen Species Scavenger to Regulate Microglial Homeostasis in Stroke

Advanced Science, EarlyView.
6 nm iron oxide nanoparticles (IONP6) exhibit enzyme‐like activities that scavenge reactive oxygen and nitrogen species (RONS), including nitric oxide (NO). In stroke models, IONP6 promotes microglial polarization toward the M2 phenotype, reduces neuroinflammation, and improves neurological outcomes, offering a promising drug‐free approach to mitigate ...
