Aggregate, Volume 6, Issue 12, December 2025.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 ...
