A Hydrogen Sulfide–Releasing Dynamic Hydrogel Modulates Coordinated Neurovascular, Immune, and Angiogenic Responses for Scar‐Suppressed Diabetic Wound Repair

open access: yesAdvanced Science, EarlyView.
ROS‐Responsive H2S Hydrogel (HAPPF) Coordinated Regeneration for High‐Quality Diabetic Wound Repair.A self‐regulating dynamic hydrogel is developed to deliver a fluorogenic H2S donor in response to excessive ROS. Released H2S acts as a master regulator to resolve chronic inflammation (M2 polarization), restore VEGF‐driven angiogenesis, and rebalance ...

Ultrasound‐Recharged Sub‐Nanometer Palladium Catalysts for on‐Demand and Self‐Terminating Bioorthogonal Prodrug Activation in Cancer Therapy

open access: yesAdvanced Science, EarlyView.
Safe and precise bioorthogonal therapy of tumors was achieved by an ultrasound‐responsive heterostructured nanoreactor with on‐demand catalytic activity. Under piezoelectric catalysis, the system undergoes reversible Pd2+/Pd0 redox cycling, concurrently enabling spatiotemporally controlled prodrug activation and self‐terminating catalytic dose ...
