[Display omitted] •A novel DA fluorescent probe was developed using β-CD/N@GQDs modified with PYL.•Upon addition of PYL, the yellow emission of probe was decreased.•Attachment of DA to PYL/β-CD@ N@GQDs enhances the blue emission at 420 nm.•Using the fluorescent probe, DA can be detected down to 0.11...
