Abstract

A fluorescence turn-on probe for Cu²⁺ based on the novel copper-mediated dihydrorosamine oxidation reaction has been constructed and employed in the detection of Cu²⁺ in water, new born calf serum, and living cells, and the new copper-mediated dihydrorosamine oxidation reaction likely proceeds by a copper redox mechanism.
