Dual‐Mode Type I/II Photosensitization of a Stable Mesoporous Hydrogen‐Bonded Organic Framework for Antibacterial Therapy

Advanced Science, EarlyView.
A π‐conjugated donor–acceptor PDI monomer undergoes hydrogen‐bonded self‐assembly to form a robust mesoporous framework. The ordered molecular arrangement promotes efficient intersystem crossing and charge separation, leading to simultaneous Type I and Type II reactive oxygen species generation with a high singlet oxygen quantum yield.

Modulating the Charge Transfer Channels via Constructing Charge‐Assisted Hydrogen‐Bonded Organic Frameworks for Enhanced Photosynthesis of Hydrogen Peroxide

Advanced Science, EarlyView.
This work reports a strategy of engineering charge‐assisted hydrogen bonds to tailor charge transfer channels in HOFs, significantly improving their performance in photocatalytic H2O2 production. ABSTRACT The production of H2O2 via artificial photosynthesis is often limited by inefficient charge‐carrier separation, causing significant charge ...

Photodynamic Priming and Minocycline Overcome Chemoresistance by Reprogramming the Pancreatic Tumor Immune Microenvironment In Vivo

Advanced Science, EarlyView.
Dual priming with minocycline and photodynamic priming reprograms the pancreatic tumor microenvironment to overcome chemoresistance. By suppressing DNA repair enzyme Tdp1, inducing photooxidative damage, and enhancing irinotecan delivery via light‐activated nanoencapsulation, this strategy remodels the tumor microenvironment and drives immune ...

Tyrosinase Driven‐Intracellular Polymerization of a Porphyrin Derivative Induced Immunogenic Death of Melanoma Cells and Strengthened Photodynamic Therapy

Advanced Science, EarlyView.
This study uses tyrosinase, which is highly expressed in melanoma, to drive porphyrins to polymerize and self‐assemble within tumor cells to form retented microstructures. This process induces immunogenic death and activates immune responses (M1 macrophages, dendritic cells, CD8+T cells), turning “cold” tumors into “hot” tumors.
