Fig. 1. MoS₂-QDs promote the generation of reactive oxygen species and induce chemiluminescence with H₂O₂ in alkaline conditions. (A) Schematic illustration of ROS generation by MoS₂-QDs. (B) The CL spectrum of injection order with (a) injection of MoS₂-QDs into a mixture of H₂O₂ + NaOH, (b) injection of NaOH into a mixture of H₂O₂ + MoS₂-QDs and (c) injection of H₂O₂ into a mixture of MoS₂-QDs + NaOH. (C) The dose-dependence of H₂O₂ concentration on kinetic decay time and CL intensity by injection of MoS₂-QDs into a H₂O₂–NaOH solution. (D) The CL kinetic curve at H₂O₂ concentrations of (a) 0.01, (b) 0.025, (c) 0.05, and (d) 0.1 M.
