    This work reports a facile synthesis of nitrogen-doped amorphous carbon nanodots (N-CNDs) and their use as a fluorometric paper-based sensor for the determination of Pb2+ at a low concentration. Both solution-based and paper-based systems were... developed. The results show that the linearity ranges for Pb2+ determination were 0.010-10 mg L-1 (LOD = 0.008 mg L-1) and 0.005-0.075 mg L-1 (LOD = 0.004 mg L-1) for the solution-based and the paper-based sensors, respectively. Furthermore, the developed
