Self‐Immolative Activatable Nanoassembly toward Immuno‐Photodynamic Therapy in TME

open access: yesAdvanced Functional Materials, EarlyView.
A quinone methide‐gated, self‐immolative, H2O2‐responsive nano‐photosensitizer (Pyz/PS) is developed for targeted immuno‐photodynamic therapy. Pyz/PS selectively activates within tumor microenvironments, restores photosensitizer activity, generates ROS, and depletes intracellular GSH, enhancing oxidative stress.

Tailoring Redox Active Sites with Dual‐Interfacial Electric Fields for Concurrent Photocatalytic Biomass Valorization and H2 Production

open access: yesAdvanced Functional Materials, EarlyView.
A rationally engineered bifunctional photocatalyst is reported, which achieves simultaneous selective oxidation of biomass‐derived 5‐hydroxymethylfurfural (HMF) to 2,5‐diformylfuran (DFF) and efficient H2 evolution. By precisely positioning Au and Co3O4 on Zn3In2S6 nanosheet, dual interfacial electric fields are well constructed to spatially separate ...
