The Cover Feature shows how the crab chelates the zinc ion with its claws. The crab represents the constitutionally very simple sensor (DAT) 2 EDTA with remarkable selectivity towards Zn 2+ ions. This molecular sensor was obtained by conjugation of the fluorescence dye diaminoterephthalate (DAT) with the chelator EDTA by amide formation. The fluorescence quantum yield of the DAT chromophore is increased by a factor of six using the clamp grip; zinc turns it on! More information can be found in the Full Paper by J. Christoffers et al.
