Abstract: A novel near-infrared fluorescent probe, namely propane-2,2-diylbis(2-((E)-2-(benzo[d]thiazol-2-yl)-2-cyanovinyl)-4,1-phenylene) diacrylate (BTA), was synthesized for selective detection of cysteine over other biologically significant amino acids. Upon addition of cysteine, the probe BTA displays a dramatic increase in fluorescence… read more here.
