Abstract: | Fluorescent carbon nanoparticles (CPs), a fascinating class of recently discovered nanocarbons, have been widely known as some of the most promising sensing probes in biological or chemical analysis. In this study, we demonstrate a green synthetic methodology for generating water‐soluble CPs with a quantum yield of approximately 24% via a simple heating process using yum mucilage as a carbon source. The prepared carbon nanoparticles with an ~10 nm size possessed excellent fluorescence properties, and the fluorescence of the CPs was strongly quenched by Fe3+, and recovered by adenosine triphosphate (ATP), thus, an ‘off’ and ‘on’ system can be easily established. This ‘CPs‐Fe3+‐ATP’ strategy was sensitive and selective at detecting ATP with the linear range of 0.5 µmol L?1 to 50 µmol L?1 and with a detection limit of 0.48 µmol L?1.
