In Vivo Repeatedly Activated Persistent Luminescence Nanoparticles by Radiopharmaceuticals for Long‐Lasting Tumor Optical Imaging

Persistent luminescence nanoparticles (PLNPs) with rechargeable near‐infrared afterglow properties attract much attention for tumor diagnosis in living animals since they can avoid tissue autofluorescence and greatly improve the signal‐to‐background ratio. Using UV, visible light, or X‐ray as excitation sources to power up persistent luminescence (PL) faces the challenges such as limited tissue penetration, inefficient charging capability, or...
