A Versatile Aza-BODIPY-Based Activatable Probe for High-Contrast NIR-II Biosensing
Activatable molecular probes in the second near-infrared (NIR-II, 900−1700 nm) window are sought-after for in vivo optical imaging and biosensing. However, current molecular skeletons are confined to a limited range of dye systems, including cyanine, hemicyanine, and xanthene derivatives. Herein, we report a series o...
