摘要：

(Chemical Equation Presented) Into the blue: Hg2+-ion-triggered formation of a brightly fluorescent squaraine dye is used as a novel approach for the design of highly selective and sensitive chromofluorogenic probes for the analysis of Hg2+ ions down to concentrations below 2 ppb (see picture). Through the adsorption of the sensor on a solid support a prototype reusable test strip is also generated. © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
