title: Green synthesis of fluorescence carbon nanoparticles from yum and application in sensitive and selective detection of ATP.
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 Fe(3+), and recovered by adenosine triphosphate (ATP), thus, an 'off' and 'on' system can be easily established. This 'CPs-Fe(3+)-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).
