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

open access: yesAdvanced 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 ...

Boosting Photo‐Pyroelectric Effect via Tunable Polarization and Interfacial Defect Engineering

open access: yesAdvanced Science, EarlyView.
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.
