A fluorescence peptide-based sensor (Dansyl-His-Thr-Glu-His-Trp-NH 2 , D-P5) was synthesized by Fmoc solid phase peptide synthesis, using dansyl group as the fluorophore. The sensor exhibited different fluorescence responses and sensitive detections for copper(II), mercury(II) and zinc(II) ions as a multifunctional sensor. The detailed investigation suggested that the limits of detection were 37.6 nmol⋅L −1 , 37.8 nmol⋅L −1  and 59.4 nmol⋅L −1  for copper(II), mercury(II) and zinc(II) ions, respectively, and the highly sensitive sensor was not influenced by other species. The sensor exhibited a strong binding ability to copper(II), mercury(II) and zinc(II) ions with the binding constants of 3.23 × 10 5  L⋅mol −1 , 6.37 × 10 5  L⋅mol −1  and 6.0 × 10 4  L⋅mol −1 , respectively. The binding stoichiometries of the sensor to copper(II), mercury(II) and zinc(II) ions measured by Job's plot were all 1:1. Furthermore, The sensor has been successfully used for the detections of copper(II), mercury(II) and zinc(II) in actual water samples.
