Abstract:
We have developed an activatable red fluorescence probe for dipeptidylpeptidase-IV (DPP-IV) by precisely controlling the photoinduced electron transfer (PeT) process of a red fluorescent scaffold, SiR600. The developed probe exhibited an extremely low background signal and showed significant fluorescence activation upon reaction with DPP-IV, enabling sensitive detection of esophageal cancer in clinical specimens from cancer patients.
