Analytical applications of nanomaterials used in electrochemiluminescence (ECL)-based detection methods are reviewed. Among nanomaterials, carbon-based nanomaterials (carbon nanotubes, graphene), metal nanoparticles, quantum dots, inorganic metal complexes and conducting polymers are considered. The most common mechanisms of ECL detections are also described in this review. Finally, challenges and perspectives of the use of such materials in chemical analysis are discussed.
