Abstract:
A new fluorescent peptide probe for the detection of Zn(2+) was synthesized on the basis of zinc binding ligands in zinc enzymes. The peptide that has a unique amino acid sequence displayed a great selectivity for Zn(2+) in the presence of several transition metal ions in aqueous solution. The reversibility, binding stoichiometry, binding affinity, and pH sensitivity of the sensor were studied. Further, on-bead application of the peptide as chemosensors was demonstrated.
