“…10 The great attraction toward CL-based analytical approaches is due to its matchless benefits, involving simple and rapid detection, high sensitivity and an excellent detection limit, economical instrumentation, and broad linear dynamic ranges. Besides, the applicability of CL systems was recently extended using different helpful nanomaterials, [10][11][12][13][14] such as metal/metal oxide 15 and carbon nanostructures. 14 They can acts as emitters, catalysts or energy acceptors in CL systems, and thus can lead to a valuable improving effects on the obtained emission.…”

On the other hand, graphene quantum dots (GQDs) are shaped from small graphene segments, which have recently been turned into more interesting nanomaterials. 24,25 This attention is due to their excellent advantages, like high solubility and photo-2019 Herein, an efficient chemiluminescence (CL) reaction with a high emission intensity is reported based on a synergistic improving effect of silver nanoclusters (AgNCs) and graphene quantum dots (GQDs). First, the syntheses of AgNCs and GQDs were simply performed by the chemical reducing of AgNO3 and a thermal treatment of glucose, respectively. After the characterization steps, the beneficial behavior of the prepared nanomaterial was investigated in CL systems. The oxidation reaction of KMnO4-rhodamine B produced weak CL emission. However, the presence of AgNCs and GQDs led to a synergetic enhancing effect, and thus higher emission was obtained. A possible mechanism was investigated for this effect using absorption and fluorescence experiments. Furthermore, rabeprazole showed a relatively selective enhancing impact on the CL emission. The CL intensity was linearly increased in the rabeprazole concentration range of 4 -133 ng mL -1 with a detection limit (3Sb/m) of 1.1 ng mL -1 . The developed CL method was utilized for the measurement of Rbp in biological samples with acceptable precision and accuracy.
