“…Table 1 summarizes a comparative list of the results of DPA detection by RGO/Fe 3 O 4 -IL-MIP/GCE and other published electrochemical methods [6,37,38,39]. The comparative results indicate that RGO/Fe 3 O 4 -IL-MIP/GCE with MIP material exhibits a low detection limit and high selectivity, which are attributed to the combined effect of good conductivity and imprinting effect.…”

In this paper, we report a new composite of reduced graphene oxide/Fe3O4-ionic liquid based molecularly imprinted polymer (RGO/Fe3O4-IL-MIP) fabricated for diphenylamine (DPA) detection. RGO/Fe3O4-IL-MIP was prepared with RGO/Fe3O4 as supporter, ionic liquid 1-vinyl-3-butylimidazolium hexafluorophosphate ([VC4mim][PF6]) as functional monomer, ionic liquid 1,4-butanediyl-3,3’-bis-l-vinylimidazolium dihexafluorophosphate ([V2C4(mim)2][(PF6)2]) as cross-linker, and diphenylamine (DPA) as template molecule. Fourier transform infrared spectroscopy, thermal gravimetric analysis, scanning electron microscopy, and vibrating sample magnetometer were employed to characterize the RGO/Fe3O4-IL-MIP composite. RGO/Fe3O4-IL-MIP was then drop-cast onto a glassy carbon electrode to construct an electrochemical sensor for DPA. The differential pulse voltammetry (DPV) peak current response for 20 μM DPA of RGO/Fe3O4-IL-MIP modified glassy carbon electrode (GCE) was 3.24 and 1.68 times that of RGO/Fe3O4-IL-NIP and RGO/Fe3O4-EGDMA-MIP modified GCEs, respectively, indicating the advantage of RGO/Fe3O4-IL-MIP based on ionic liquid (IL) as a cross-linker. The RGO/Fe3O4-IL-MIP sensor demonstrated good recognition for DPA. Under the optimized conditions, the RGO/Fe3O4-IL-MIP sensor exhibited a DPA detection limit of 0.05 μM (S/N = 3) with a linear range of 0.1–30 μM. Moreover, the new RGO/Fe3O4-IL-MIP based sensor detected DPA in real samples with satisfactory results.

“…The introduction of metal dopants or nanoparticles into TMDs often helps to enhance electrocatalytic activities, improves charge transfer rates, and tunes sensing performances, causing metal-TMDs composites to find wide applications in the field of electrically transduced chemical sensors. [176,177] An ultrasensitive electrochemical dopamine sensor based upon manganesedoped MoS 2 (Figure 6A) was developed by Lei et al In the study, the author first performed an electrochemical impedance study to yield a better comprehension of the electrode/solution interface and the electrochemical reactions with dopamine. By fitting the Nyquist plots with a Randles equivalent circuit, the charge transfer resistance of pristine MoS 2 and manganesedoped MoS 2 are calculated to be (7.10 ± 0.4) × 10 4 and (4.49 ± 0.5) × 10 4 Ω, respectively, suggesting that the manganese-doped MoS 2 sensor possesses more favorable kinetics.…”

The rapid advancements in the field of materials science, especially nanoscience, have played a critical role in the advancement of sensors, in particular the development of novel transducer platforms. Sensors are devices that respond to specific phenomena with recordable and analytically useful output signals and have found their way into a myriad of applications in daily life. Some of these applications include the measurement of glucose and cholesterol levels and detection of emerging infectious diseases for biomedical purposes, environmental monitoring, and food analysis. 2D materials proffer numerous advantageous physical, chemical, electronic, and optical attributes such as large specific surface areas, excellent electrical and thermal conductivity, an abundance of catalytic sites, ease of functionalization, and tuneable electronic structures, allowing them to hold promising potential for the development of sensors with high sensitivity. Although layered materials demonstrate many beneficial attributes for the development of sensors, the properties and electronic structure of layered materials can be fine‐tuned via doping or decorating to enhance the sensing performance. This review highlights the current progress of electrical and optical sensors based upon metal‐decorated and metal‐doped 2D materials and examines the effects of decorating and doping 2D materials for sensor developments.

“…Such single or few layered 2D MoS 2 and MoSe 2 have been extended for the various electrochemical applications . Comparatively, MoSe 2 exhibits the higher electro catalytic activity and electrical conductivity than MoS 2 because of the superior metallic property with electrocatalytic active unsaturated edge of Se Thus, MoSe 2 is extended for catalysis, optoelectronics and supercapacitor application . Very recently, Chen et al., demonstrated the higher electro‐catalytic nature of MoSe 2 by doping europium and strontium for detection of diphenylamine and metronidazole respectively.…”

“…Although various techniques like chemical vapor deposition , mechanical exfoliation hydrothermal and various other methods were developed for synthesis of novel materials, hydrothermal method yields higher active sites in the nanostructure of MoSe 2 as rod‐, tube‐ and sheet‐like nanomaterials . But MoO 3 always co‐exists as minor by‐product in the hydrothermally synthesized MoSe 2 and such MoSe 2 −MoO 3 heterostructure can enhance the catalytic performance of the material.…”

The present work reports a simple and single‐step hydrothermal synthesis of MoSe2−MoO3 composite for highly sensitive and selective electrochemical oxidation of nitrite. FESEM of the MoSe2−MoO3 hybrid revealed the formation of composite as laminated structure of different sizes piled up together as finger‐like MoSe2 bars whilst other physico‐chemical characterizations (XRD, FTIR, UV‐Vis, XPS) confirmed that co‐existence of MoO3 as a major by‐product of hydrothermal synthesis. The as‐fabricated MoSe2−MoO3 composite based nitrite sensor showed remarkable selectivity and reproducibility with <3s of response time, excellent sensitivity and detection limit of 10.84 A M−1 cm−2 (R2=0.996) and 0.1 μM, respectively, in the range of 2.5–80 μM. The obtained sensitivity can be credited to the high surface area obtained from 1T phase MoSe2 and α phase MoO3 as the sensing material. The developed sensor was effectively evaluated for electrochemical recognition of nitrite in the water samples (potable and tap water) gathered from an industrial area. This new and efficient MoSe2−MoO3 based electrode material offers a new frontier for the progress of a novel composites by simple and single‐step approach which can be used for progress of non‐enzymatic and inexpensive electrochemical sensors for a wide range of analytical applications.
