Synthesis of N-CQDs and its sensing mechanism for Fe3+, AA and H2O2. [Display omitted] •A simple “on-off-on-off” continuous response fluorescence sensor was developed.•The analytical process is fast, and the three inputs “Logic gate” is achieved. In this study, an environmentally friendly and water-...
