A Metalloporphyrin Nanosystem Enables Non‐Invasive Visualization and Specific Treatment for Thrombosis and Ischemic Stroke

Advanced Science, EarlyView.
Thrombotic ischemic stroke is a severe neurological disease of the brain that presents major challenges for effective diagnosis and treatment. Precisely engineered Ir and Mn cores within a single porphyrin framework of 4IrMn nanoparticles enable endogenous ONOO−‐ or laser‐activated switching among NIR‐CL imaging, photothermal / photodynamic therapy ...
