“…It was proposed that gold nanomaterials can not only improve the electron transfer but also catalyze the electro‐reduction of S 2 O 8 2− . Furthermore, Li et al hybridized g‐C 3 N 4 with silver nanoparticles (AgNPs) rather than AuNPs . In general, the effects of AgNPs are quite similar with those of AuNPs.…”

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.

“…This was due to the fact that OOH produced by dissolved O 2 reacted with SO 4 À to obtain (O 2 ) 2 *, which acted as lightemitting species to generate ECL emission [40]. This phenomenon was previously reported by Ou et al [12] and Li et al [41]. With the assembly of Ag-g-C 3 N 4 onto the surface of GCE, a high ECL signal was obtained (curve b), confirming the successful immobilization of Ag-g-C 3 N 4 on the electrode.…”

“…In most cases, the sensing principle was based on the inhibition effect due to the presence of the target, which blocked the electron transfer on the electrode interface, such as the determination of proteins . In order to amplify quenching effect, Wei's group recently employed the ferrocene as quencher for g‐C 3 N 4 ECL emission and fabricated a sensitive sensing platform for CEA detection. Alternatively, signal‐on ECL biosensors based on g‐C 3 N 4 were also developed.…”

(ECL) is chemiluminescence that is triggered by electrochemical techniques, and it has received broad applications because of its advantages, such as high sensitivity and wide dynamic range. In recent years, some novel luminescent nanomaterials have been developed and widely used to fabricate ECL biosensors with the development of nanoscience and nanotechnology. This Review presents a general description of luminescent nanomaterials as ECL emitters from the last five years, including semiconductor quantum dots (QDs), carbon-based materials, metal nanoclusters (NCs), and upconversion nanoparticles (UCNPs). The basic mechanisms, developments, and applications of these materials are given. Finally, we conclude with a brief look at the future challenges and prospects in the development of ECL sensors.
