Electrochemiluminescence (ECL) is chemiluminescence resulting from electrochemical reactions. In comparison with conventional chemiluminescence, ECL exhibits several advantages such as facile spatial and temporal control, good reproducibility, stable reagent, electrochemical tunability and capability of electrochemical signal amplification. As a result, ECL has being extensively studied and has broad analytical applications. Nanomaterials play versatile roles in ECL as luminophores, catalyst, quenchers, immobilization matrixes, and so on [1-3].

Herein, the syntheses and analytical applications of some nonmetallic nanomaterials is presented, such as ultrasensitive glutathione detection using MnO2 nanosheets, ozone detection by Ru(phen)32+-doped silica nanoparticles, ATP aptasensor based on single-walled carbon nanohorn quencher, immobilization of ruthenium complexes with graphene materials, oxide nanofilm-covered stainless steel electrode for enhancing sensitivity [4-10].
