Here base on competitive interaction of electrostatic repulsion and π–π stacking, noncovalent assembly of carbon nanoparticles (cCNPs) with aptamer that allows sensitive and selective detection of ATP is reported. The sensor exhibits minimal background fluorescence and rapid kinetics response depending on the spherical structure of cCNPs.
