title = "A highly selective “ON-OFF” probe for colorimetric and fluorometric sensing of Cu2+ in water",
abstract = "We present herein a diformyl phenol based probe, 3-(\{3-[2,3-dihydroxy-propylimino-methyl]-2-hydroxy-5-methyl-benzylidene\}-amino)-propane-1,2-diol (H5dpm), as a colorimetric and fluorometric chemosensor for selective detection of Cu2+ in aqueous solution under physiological conditions. This simple system produces a colorimetric change enabling naked eye detection as well as on-off fluorescence response towards Cu2+ in an aqueous medium with a detection limit of 11.2 nM. To further demonstrate the utility of H5dpm, we next explored the application of H5dpm for imaging Cu2+ in Vero cells. The attractive imaging properties of the H5dpm probe will open up avenues for molecular imaging and biomedical applications.",
