Aggregation‐Induced Triplet Symmetry‐Breaking Charge Separation Drives Electron Transfer for Autophagy Blockade‐Enhanced Type‐I Photodynamic Therapy

Aggregate, EarlyView.
This study presents a novel class of cyanine‐based photosensitizers (PS) to achieve controllable switching between Type‐I and Type‐II mechanisms during photodynamic therapy. The formation of radical ion pairs (PS•+−PS•−) via symmetry‐breaking charge separation in aggregated systems at the triplet state, triggering Type‐I cascade reactions for effective

Aggregation‐Enhanced Asymmetric Heptamethine Cyanine Nanoplatform for Imaging‐Guided Synergistic Phototherapy and Ferroptosis

Aggregate, EarlyView.
An asymmetric heptamethine cyanine photosensitizer, Cyp‐TPE, is designed to break molecular symmetry and form ordered nanoaggregates, resulting in ultrahigh ROS generation and synergistic photothermal/photodynamic activity. It further triggers ferroptosis and lysosomal dysfunction, providing a potent aggregate‐based theranostic platform for imaging ...

Bacterial DNA‐Targeting AIE Photosensitizer for Efficient Eradication of Intracellular Bacteria and Biofilm‐Associated Infections

Aggregate, EarlyView.
A bacterial DNA‐targeted PS TPE‐CN for the precise treatment of MRSA‐associated infections has been developed. Through synergistic PDT effect, TPE‐CN damages bacterial DNA and membrane, resulting in effective elimination of planktonic bacteria, biofilm, and intracellular bacteria.
