An ESIPT-ICT synergistic near-infrared probe for selective detection of Cys in HeLa cells and zebrafish.
As a small molecule thiol, cysteine (Cys) plays a vital role in living organisms. It can stabilize the cellular redox state, maintain metabolic balance, and participate in the regulation of multiple physiological and pathological processes. Therefore, constructing fluorescent probes for the specific sensing of Cys is o...
