A novel electrochemiluminescence resonance energy transfer system of luminol-graphene quantum dot composite and its application in H2O2 detection

Luminol-nitrogen doped graphene quantum dots (luminol-NGQDs) nanocomposite was synthesized and a novel electrochemiluminescence resonance energy transfer (ECL-RET) process was found between luminol and NGQDs inside the composite. Hydrogen peroxide enhanced luminol-NGQDs ECL signal significantly based on the production of superoxide radical.163
