“…Alternatively, metal NSs can be attached to MoS 2 via noncovalent interactions. Electrostatic interactions are the commonly utilized noncovalent approaches in the syntheses of MoS 2 -based nanocomposites [ 69 , 81 , 82 ]. Absorption of MoS 2 is often achieved via surfactant functional groups attached to the surface of metal and metal oxide NSs.…”

“…Au NPs were distributed randomly on the layered surface structures of MoS 2 nanosheets. On the other hand, the MoS 2 -CuO nanocomposite ( Figure 2 d) obtained by stirring the two nanomaterials for hours showed the reduced CuO nanotube aggregation [ 82 ]. The agglomeration of the NPs may appear to have had negative impacts on the properties of the nanocomposite.…”

“…The exceptionally large surface areas of 2D MoS 2 nanosheets offer robust surface functionalization and provide new possibilities for functional devices based on 2D materials. MoS 2 has been reported to simply form nanocomposites with metal and metal oxide NSs [ 69 , 82 ], carbon nanomaterials [ 137 , 138 ], conductive polymers [ 139 , 140 , 141 ], and other 2D nanomaterials [ 142 , 143 ], which could be used as catalytic materials to significantly increase the electrochemical performance of sensors based on MoS 2 -nanocomposites. The 2D MoS 2 /metal-NS composites have the inherent properties of pure metal NSs and MoS 2 nanosheets due to their synergistic effects, which makes the 2D MoS 2 /metal-NS composites exhibit outstanding electrochemical properties and improved sensitivity [ 13 ].…”

“…Controlling the interactions of enzymes with the substrate to improve electron transfer processes remains a challenge that causes a substantial loss of GOx activity, leading to poor overall performance of the sensor. Therefore, other researchers saw an opportunity to explore various 2D MoS 2 /metal-NS composites (Ni-MoS 2 [ 35 ], CuO-MoS 2 [ 82 ], Cu-MoS 2 [ 85 ], Au-Pd/MoS 2 [ 89 ], Cu 2 O-MoS 2 [ 93 ], NiO-MoS 2 [ 103 ], NiCo 2 O 4 -MoS 2 [ 108 ], and MoS 2 -PPY-Au [ 206 ]) as electrode materials to construct non-enzymatic sensors due to their extraordinary electrocatalytic activities, excellent conductivity, and large surface areas. The experimental results revealed that the performances of all these 2D MoS 2 /metal-NS composites were remarkable, as shown in Table 2 .…”

Two-dimensional transition metal dichalcogenides (2D TMDs) have gained considerable attention due to their distinctive properties and broad range of possible applications. One of the most widely studied transition metal dichalcogenides is molybdenum disulfide (MoS2). The 2D MoS2 nanosheets have unique and complementary properties to those of graphene, rendering them ideal electrode materials that could potentially lead to significant benefits in many electrochemical applications. These properties include tunable bandgaps, large surface areas, relatively high electron mobilities, and good optical and catalytic characteristics. Although the use of 2D MoS2 nanosheets offers several advantages and excellent properties, surface functionalization of 2D MoS2 is a potential route for further enhancing their properties and adding extra functionalities to the surface of the fabricated sensor. The functionalization of the material with various metal and metal oxide nanostructures has a significant impact on its overall electrochemical performance, improving various sensing parameters, such as selectivity, sensitivity, and stability. In this review, different methods of preparing 2D-layered MoS2 nanomaterials, followed by different surface functionalization methods of these nanomaterials, are explored and discussed. Finally, the structure–properties relationship and electrochemical sensor applications over the last ten years are discussed. Emphasis is placed on the performance of 2D MoS2 with respect to the performance of electrochemical sensors, thereby giving new insights into this unique material and providing a foundation for researchers of different disciplines who are interested in advancing the development of MoS2-based sensors.

“…The sensors was successfully tested in real blood samples. The glucose sensing properties of Mo layered materials can be further enhanced by combining them with metal NPs such as Pt, Au, Ni, or Cu, exploiting the high electrochemical oxidation to glucose of these additives [69,70]. Noble metals display large catalytic activity at physiological pH (near to 7), but they have a high cost compared to Cu or Ni.…”

Mo-based layered nanostructures are two-dimensional (2D) nanomaterials with outstanding characteristics and very promising electrochemical properties. These materials comprise nanosheets of molybdenum (Mo) oxides (MoO2 and MoO3), dichalcogenides (MoS2, MoSe2, MoTe2), and carbides (MoC2), which find application in electrochemical devices for energy storage and generation. In this feature paper, we present the most relevant characteristics of such Mo-based layered compounds and their use as electrode materials in electrochemical sensors. In particular, the aspects related to synthesis methods, structural and electronic characteristics, and the relevant electrochemical properties, together with applications in the specific field of electrochemical biomolecule sensing, are reviewed. The main features, along with the current status, trends, and potentialities for biomedical sensing applications, are described, highlighting the peculiar properties of Mo-based 2D-nanomaterials in this field.

The electrodeposition method was firstly applied to obtain uniform cube‐shaped copper nanoparticles on conductive glass (ITO), and then a layer of tiny nickel nanoparticles. A bimetallic composite electrode (Cu−Ni/ITO), characterized by TEM, XPS and XRD, was prepared to construct the non‐enzyme electrochemical glucose sensor with high catalytic activity. The catalytic performance of Cu−Ni/ITO had been greatly improved, probably due to the synergistic bimetallic catalysis effect. The electrode had a satisfactory linear response in the range of 2.5×10−7 M to 2.6×10−3 M, with detection limit as low as 67 nM. Besides, Cu−Ni/ITO had good anti‐interference ability and reproducibility, indicating the promising application for glucose detection in practical samples.
