An ultrasensitive electrochemiluminescence (ECL) biosensor for detecting dopamine was successfully constructed based on chemically stable and easily available carbon nitride materials as signal probe. Herein, the newly synthesized silver‐carbon nitride (Ag−g−C3N4) nanocomposites were modified on the glassy carbon electrode (GCE) surface via the film‐forming properties of chitosan, generating a relative weak ECL signal. When dopamine was added to the detection solution containing 80 mM S2O82−, a strong ECL signal was observed, which might be ascribed to the fact that the amino group of dopamine promoted the coreactant conversion of S2O82− into SO4.−, leading to enhanced ECL intensity. Under optimal experimental conditions, the as‐prepared ECL sensor exhibited a wide linear range from 0.015 to 150 μM and a low detection limit of 0.005 μM for dopamine determination. Moreover, the recovery experiments exhibited that the sensor can be applied to precisely detect dopamine in real serum samples, suggesting that the as‐prepared ECL sensor established a new method and a promising platform for sensitive dopamine evaluation.

In recent years, graphitic carbon nitride (g-C 3 N 4) has attracted much attention due to its unique properties and excellent performance in the field of sensors, which has inspired the authors to compile this review. Although there are many reviews on the synthesis and applications of g-C 3 N 4 materials, a targeted, systematic, comprehensive summary of applications in sensors and the sensing mechanisms of g-C 3 N 4-based nanomaterials have not been published. In this review, the preparation methods and synthetic conditions for preparing g-C 3 N 4 with different morphologies, such as conventional bulk g-C 3 N 4 , g-C 3 N 4 nanosheets, and g-C 3 N 4 quantum dots, are introduced in detail. By reviewing recent advances in g-C 3 N 4-based nanomaterials in ion sensors, biosensors, gas sensors and humidity sensors, this study provides more comprehensive and in-depth information for the further design of g-C 3 N 4based sensors with enhanced performance. A brief outlook of g-C 3 N 4-based sensors is presented as the conclusion of this review.
