title: A protein-supported fluorescent reagent for the highly-sensitive and selective detection of mercury ions in aqueous solution and live cells.
abstract: A fluorescent sensor, dansyl-l-aspartic acid (1), coupled with BSA was used to specifically detect Hg2+ in a neutral aqueous solution as well as in live cells; the fluorescence emission spectrum underwent an obvious blue shift with an enhancement in fluorescence intensity, and these effects were evident as color changes in fluorescence imaging pictures.
