Electrochemiluminescence bioassays based on carbon nitride nanomaterials and 2D transition metal carbides

Electrochemiluminescence (ECL) is a powerful technique for bioassays. To meet the growing demand for bioassays, it is necessary to develop new ECL emitters and co-reaction acceleration strategies to improve detection sensitivity and expand the application scope. Carbon nitride nanomaterials and 2D transition metal carbides, as newly emerging carbon-based nanomaterials, have been increasingly used for ECL bioassays due to their attractive optical and electrochemical properties as well as diversity. In this minireview, we summarized the latest advances in ECL bioassays using carbon nitride nanomaterials and 2D transition metal carbides in the past two years. Finally, we briefly discuss the future trends and challenges of carbon-based nanomaterials for ECL bioanalysis. • ECL bioassays based on carbon nitride nanomaterials and 2D transition metal carbides were reviewed. • Carbon nitride nanomaterials and 2D transition metal carbides have features of attractive properties and diversity. • Future trends and challenges of both nanomaterials for ECL bioanalysis are proposed.
