Design of quinoline-based fluorescent probe for the ratiometric detection of cadmium in aqueous media

A new fluorescent probe, DQCd2, based on 4-piperidinoquinoline has been synthesized as a fluorescent probe for Cd2+. It can ratiometrically respond to Cd2+ in PBS buffer by a remarkable emission intensity enhancement (88-fold) and wavelength shift (70 nm).

A new fluorescent probe is capable of responding to Cd2+ with a significant turn-on and ratiometric fluorescence signal output in aqueous solution.Figure optionsDownload as PowerPoint slide
