“…However, conventional prodrug nanocarriers lack imaging capability, making it challenging to track their biodistribution or locate tumor sites accurately. To address this, prodrug nanocarriers with stimuli-responsive fluorescent probes, like those exhibiting aggregation-induced emission (AIE) or aggregation-induced quenching (ACQ) properties, have attracted significant attention. − Moreover, magnetic resonance imaging (MRI) is widely used in medical imaging due to its noninvasiveness, high penetration depth, and absence of harmful ionizing radiation. , Conventional 1 H MRI provides anatomical images of soft tissues using contrast agents. , As a complement to 1 H MRI, 19 F MRI selectively and quantitatively detects exogenous fluorinated probes without background interference. − As a result, 19 F MRI offers quantitative “hot-spot” images of targeted tissues through anatomical localization provided by 1 H MRI. , …”
