Encapsulating Cu NCs with aggregation-induced emission into metal–organic framework ZIF-8 as a novel fluorescent nanoprobe for the highly sensitive detection of felodipine

Cu NCs@ZIF-8 was prepared by encapsulating Cu NCs with AIE effects into the ZIF-8 through electrostatic attraction. A novel fluorescent nanoprobe was developed for the sensitive detection of felodipine via the inner-filtration effect mechanism.
