Abnormal concentrations of Cys have been reported to be implicated in various health problems, including cancer, neuropathy, and cardiomyopathy. We present a novel two-photon fluorescent probe for the specific recognition of cysteine over homocysteine and glutathione, and the bioapplication of this probe for the imaging of live cancerous cells and thick tissues.
