講座內容：

Optical imaging plays a crucial role in biology and medicine. However, the need for real-time light excitation during imaging produces tissue autofluorescence, and thus compromises imaging sensitivity and specificity. Meanwhile, optical agents are often retained in living bodies, posing additional toxicity issue. In this talk, I will introduce molecular afterglow reporters with long-lasting luminescence after removal of light excitation for ultrasensitive in vivo imaging, followed by discussion on how to design renal-clearable optical reporters for early diagnosis of kidney diseases. The in vivo afterglow of SPNs has the signal to background ratio more than two orders of magnitude higher than NIR fluorescence, enabling rapid detection of tiny peritoneal metastatic tumors. The structural diversity of SPNs allows them to monitor temperature during photothermal cancer therapy and detect biomarkers of interest in living mice. To detect acute kidney injury (AKI), molecular renal probes (MRPs) with high renal clearance efficiency are developed. MRPs specifically activate their NIR/chemiluminescence signals towards the prodromal biomarkers of AKI, enabling the first example of longitudinal imaging of multiple molecular events in the kidneys of living mice. MRPs also act as exogenous tracers for optical urinalysis that outperforms typical clinical/preclinical assays. These studies thus provide the basis for an entirely new class of molecular optical reporters with ultrahigh sensitivity and high translational potential for early diagnosis.
