“…The nanocomposite was recommended as a sensing material for biomedical and clinical applications [ 89 ]. Similarly, Ngo and co-workers reported highly biocompatible phenylboronic acid-functionalized graphitic carbon nitride quantum dots to detect glucose [ 90 ]. Here, the graphitic carbon nitride (g-C 3 N 4 ) was used as a fluorescent nanomaterial, while the phenylboronic acid acted as the quencher and the receptor for the glucose sensor [ 90 ].…”

“…The constructed biosensor’s selectivity was evaluated on ascorbic acid, sorbitol, dopamine, L-cystine, and other saccharides present in real blood. All the biologic molecules showed no significant response towards g-CNDs/PBA; this is due to the specific reaction between glucose and PBA by the presence of a cis-diol pair at the 1,2-and 5,6- positions in glucose [ 90 ].…”

Graphitic carbon nitride (g-C3N4) is a two-dimensional conjugated polymer that has attracted the interest of researchers and industrial communities owing to its outstanding analytical merits such as low-cost synthesis, high stability, unique electronic properties, catalytic ability, high quantum yield, nontoxicity, metal-free, low bandgap energy, and electron-rich properties. Notably, graphitic carbon nitride (g-C3N4) is the most stable allotrope of carbon nitrides. It has been explored in various analytical fields due to its excellent biocompatibility properties, including ease of surface functionalization and hydrogen-bonding. Graphitic carbon nitride (g-C3N4) acts as a nanomediator and serves as an immobilization layer to detect various biomolecules. Numerous reports have been presented in the literature on applying graphitic carbon nitride (g-C3N4) for the construction of electrochemical sensors and biosensors. Different electrochemical techniques such as cyclic voltammetry, electrochemiluminescence, electrochemical impedance spectroscopy, square wave anodic stripping voltammetry, and amperometry techniques have been extensively used for the detection of biologic molecules and heavy metals, with high sensitivity and good selectivity. For this reason, the leading drive of this review is to stress the importance of employing graphitic carbon nitride (g-C3N4) for the fabrication of electrochemical sensors and biosensors.

Today, tris‐s‐triazine based graphitic carbon nitride (g‐C3N4) is a new research hot topic. It has a unique electronic band structure, high physicochemical stability, large surface area, and is “earth‐abundant.” These and other properties have made it a highly researched material especially for visible light photocatalysis and photodegradation applications and as the starting material from which to develop novel electrochemical sensing platforms. In this review, the state‐of‐the‐art technologies utilizing tris‐s‐triazine graphitic carbon nitride as a tailorable signal‐transducing nanostructured material for sensing applications is presented in detail. Initially, the electronic structure of g‐C3N4, morphologies, doping, heterojunctions, its combination with other carbon materials, and defect formation, is described, which is followed by a discussion on its role in electrochemiluminescence, photoelectrochemical, fluorescence sensors and gas sensors as a signal transducer with appropriate examples. This review concludes with a discussion summarizing state‐of‐the‐art and both future perspectives and challenges at the cutting edge of this research.
