A novel barbiturate-based fluorescent probe for selective detection of Cu2+ in aqueous media and live-cell imaging.
A novel barbiturate-naphthyl-picolinate conjugate as a fluorescent probe for the selective detection of Cu2+ in an aqueous media and was successfully employed for fluorescence imaging of intracellular Cu2+ in living 4 T1 cells, indicating its potential utility for biological sensing and bioimaging applications.
