Ratiometric fluorescence monitoring of cerebral Cu2+ based on coumarin-labeled DNA coupled with the Cu2+-induced oxidation of o-phenylenediamine†
Abstract
A novel and facile ratiometric fluorescence method for evaluating Cu2+ has been developed based on coumarin-labeled single-stranded DNA (C-ssDNA) coupled with the Cu2+-induced oxidation of o-phenylenediamine (OPD). By combining the microdialysis technique, the ratiometric fluorescence method has also been successfully exploited to monitor the cerebral Cu2+ in the rat brain, promising new opportunities for studying the cerebral Cu2+-associated physiological and pathological events.
