title: Rhodamine-sugar based turn-on fluorescent probe for the detection of cysteine and homocysteine in water.
abstract: A new turn-on fluorescent probe utilizing the "chemosensing ensemble" method is developed to detect thiol-containing amino acids. A complex of Au(+) and a rhodamine hydroxylamine having 2-deoxyribose can selectively detect cysteine and homocysteine in water.
