“…However, poor electrochemical responses of ACTM at bare working electrodes are remarkably considered as the limitation of such electrochemical sensing techniques. One strategy to improve the signal is to modify the electrodes with various functional materials including noble metal nanoparticles (NPs) [15,16], metal oxides [17,18], polymers [19,20], carbon materials [21,22], natural enzyme [23]. Among these materials, graphene (including reduced graphene oxide or RGO) and metal NPs have been subjected to intense research studies due to their unique structures and intrinsic properties.…”

Over the past years, the development of electrochemical sensing platforms for the sensitive detection of drug molecules have received great interests. In this research study, we introduced cauliflower‐like platinum particles decorated reduced graphene oxide modified glassy carbon electrode (Pt−RGO/GCE) as an electrochemical sensing platform for highly sensitive determination of acetaminophen (ACTM). The sensor was prepared via a simple and environmentally friendly two‐step electrodeposition method at room temperature. The combination of conductive RGO nanosheets and unique structured Pt particles (average 232 nm in diameter) provided an efficient interface with large effective surface area which greatly facilitated the electron transfer of ACTM. The experimental conditions that might affect the drug detection were studied in detail and optimized for best performance. The Pt−RGO/GCE was able to detect ACTM up to the limit of 2.2 nM with a linear concentration range from 0.01 to 350 μM. With its high reproducibility, excellent stability and selectivity, the as‐fabricated sensor was successfully applied to the ACTM content measurement in commercial tablets.

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.

“…Graphitic carbon nitride (g‐C 3 N 4 ) nanoparticles appeared to be highly active material for electrochemical sensing applications because of their special attributes like large surface area, substantial electrical conductivity and good thermal stability [38]. Graphitic carbon nitride (g‐C 3 N 4 ) possesses considerable electrocatalytic properties and has been reported as an electron modifier between electroactive target analyte and the electrode surface, which result in accelerating the electron transfer in an electrochemical reaction [39, 40]. The presence of different reactive groups on g‐C 3 N 4 surface can enhance the electron transfer rate and thereby reduce the overpotential of target analyte and enhance sensitivity [41, 42].…”

Development of nanocomposite based electrochemical sensors for detection of toxic chemicals describes an environmentally benign strategy for monitoring the health of ecosystem. Herein, we reported in situ preparation of graphitic carbon nitride (g‐C3N4) decorated Ag2S/NiFe2O4 nanocomposite sensor by facile precipitation method. The electrochemical studies demonstrated efficient electrocatalytic activity of ternary nanocomposite pasted glassy carbon electrode (g‐C3N4@Ag2S/NiFe2O4/GCE) for selective detection of formaldehyde. Moreover, fabricated sensor exhibit rapid amperometric response with excellent selectivity, remarkable sensitivity (1681 μA mmol L−1 cm−2) and lower detection limit (LOD: 1.63 μmol L−1). It is noteworthy to mention that sensor exhibits good operational and long‐term storage stability.
