“…With the unique advantages of graphene-like 2D materials mentioned above, it is desirable to harness their properties in composites through the incorporation with various kinds of functional materials. The introduction of this functional materials attracted great interest due to the synergistic contribution among different components (Campuzano et al 2016;Vasilescu et al 2016). With appropriate designs, nanocomposites can offer more opportunities for the surface functionalization, enhancement of the conductivity and electron transfer rate, and thus improve their electrochemical performances in biosensing applications with Au NPs to construct a robust biointerface, which was used to fabricate a signal amplified electrochemical DNA biosensor (Huang et al 2014a).…”

of 18) 1605817As a newly emerging class of nanomaterials, 2D TMD nanosheets possess a unique layered structure and large surface areas, as well as outstanding physical, chemical, optical, and electronic properties, which holds great potential for applications in catalysis, [37] sensing, [38] optics, [39] and energy. [40] In this review, we will focus on the introduction of state of the art sensing applications for 2D TMD nanosheets and their composites. In particular, different sensing strategies together with signal-transducing mechanisms in sensors based on 2D TMD nanosheets and their composites are thoroughly discussed. Our aim is to demonstrate a complete concept in this rapidly emerging research area and to address basic knowledge, opportunities, and challenges in this promising field. We expect that more 2D TMD nanosheets and their composites, as well as more sensing strategies, will be explored in this research field, enabling the fabrication of more accurate sensing devices for practical applications. TMD Nanosheets and Their Composite-Based Electrochemical SensorsThe electrochemical method has been extensively recognized as a powerful tool for fast access to biochemical information in complex samples due to its easy operation, fast response, high sensitivity, and low cost. Inspired by the use of graphene as transducers in electrochemical sensors, [41][42][43] researchers have attempted to use 2D TMD nanosheets as a transducer layer. Their good conductivity, large surface area, fast electron transfer kinetics, high signal/noise ratio, and, more importantly, their feasibility for forming composites, make 2D TMD nanosheets attractive as for electrochemical sensors. [44][45][46][47][48][49][50] Table 1 summarizes the recent progress of electrochemical sensors based on 2D TMD nanosheets and their composites. TMD Nanosheets as a Transducer Layer in Electrochemical SensorsIn 2012, our group developed a single-layer TMD-nanosheetbased electrochemical sensor, in which a single-layer MoS 2nanosheet-modified glassy carbon electrode was directly used for selective detection of dopamine in the presence of uric acid Two-dimensional (2D) transition metal dichalcogenide (TMD) nanosheets, such as MoS 2 , WS 2 , etc., are attracting increasing interest due to their intriguing physical, chemical, electronic, and optical properties. Success in development of methods for large-scale production of 2D TMD nanosheets and their composites has given great potential for various novel applications. In this review, recent progress in sensing applications of 2D TMD nanosheets and their composites is introduced. Moreover, different sensing strategies and signal-transducing mechanisms for sensing devices based on 2D TMD nanosheets and their composites are also summarized and discussed.
