“…More and more attentions have been focused on hybridizing g‐C 3 N 4 with some other nanomaterials, such as conductive graphene oxide (GO) and some noble metal nanomaterials, to improve the electron transfer and amplify the ECL signal of g‐C 3 N 4 . For example, Xia et al prepared g‐C 3 N 4 /GO hybrid by directly mixing g‐C 3 N 4 nanosheets with GO solution by ultrasonication . Li et al oxidized g‐C 3 N 4 with concentrated nitric acid into carboxylated g‐C 3 N 4 , then prepared g‐C 3 N 4 /GO hybrid through electrostatic interactions between positively charged poly(diallyldimethylammonium) chloride and negatively carboxylated g‐C 3 N 4 and GO .…”

“…Their experimental results indicated that GO is helpful to amplify the ECL response of g‐C 3 N 4 . For instance, Xia et al found that the ECL intensity of g‐C 3 N 4 /GO was about 3.8 times higher than that of g‐C 3 N 4 . Furthermore, the ECL onset potential of g‐C 3 N 4 /GO was more positive than that of g‐C 3 N 4 .…”

Graphitic carbon nitrides (g-C N ) are a class of 2D polymeric materials mainly composed of carbon and nitrogen atoms. g-C N are attracting dramatically increasing interest in the areas of sensing, imaging, and therapy, due to their unique optical and electronic properties. Here, the luminescent properties (mainly includes photoluminescence and electrochemiluminescence), and catalytic and photoelectronic properties related to sensing and therapy applications of g-C N materials are reviewed. Furthermore, the fabrication and advantages of sensing, imaging and therapy systems based on g-C N materials are summarized. Finally, the future perspectives for developing the sensing, imaging and therapy applications of the g-C N materials are discussed.

“…With the discovery, the same group developed a series of surface‐enhanced ECL based biosensors . For example, an ultrasensitive ECL sandwich immunosensor was constructed for carcinoembryonic antigen (CEA) detection by using novel signal reporting tags that were prepared through layer‐by‐layer assembly of Ru(bpy) 3 2+ ‐doped silica nanoparticles (Ru@SiO 2 ) as ECL emitters and Au NPs as LSPR source . The ECL enhancement increased as increasing of the assembly layer of Ru@SiO 2 ‐Au NP nanoarchitectures.…”

[62] The ECL enhancement increased as increasing of the assembly layer of Ru@SiO 2 -Au NP nanoarchitectures. Under the optimal condition, the ECL sensor pushed the detection limit of CEA in human serum to be 1.52 × 10 À 6 ng mL À 1 .…”

Searching biocompatible electrochemiluminescence (ECL) co‐reactants for tris(2,2’‐bipyridyl)ruthenium(II) (Ru(bpy)32+), a classical ECL reagent, has attracted extensive attention to expanding its analytical applications and improving sensing performances. Advances in nanomaterial science promote the discovery of novel co‐reactants and new enhancement mechanisms for Ru(bpy)32+ ECL. In this Minireview, we discuss the current progress in Ru(bpy)32+‐nanomaterial co‐reactant ECL with an emphasis on enhancement mechanisms and sensing strategies developed. Four kinds of nanomaterials for Ru(bpy)32+ ECL enhancement are classified into two groups, according to the working mechanisms and presented in the order of novelty. Perspectives on the promises and challenges facing this field are also discussed.

Graphitic carbon nitride (g-C 3 N 4 ) has attracted considerable attention due to its special structure and properties, such as its good chemical and thermal stability under ambient conditions, low cost and non-toxicity, and facile synthesis. Recently, g-C 3 N 4 -based sensors have been demonstrated to be of high interests in the areas of sensing due to the unique optical, electronic and catalytic properties of g-C 3 N 4 . This review focuses on the most salient advances in luminescent sensors based on g-C 3 N 4 , chemiluminescence, cataluminescence and electrochemiluminescence methods are discussed. This review provides valuable information for researchers of related areas and thus may inspire the development of more practical and effective approaches for designing two-dimensional (2D) nanomaterial-assisted luminescent sensors.
