“…Improved spatial distributions of NPs on the surface of the MoS 2 nanosheet not only increase the synergistic effect and active surface area but also have the potential to control the charge carrier density [ 88 , 122 ]. As a result of enhanced electrical conductivity and electron mobility, as well as a large active surface area, biological molecules can be effectively immobilized on MoS 2 for the detection of target analytes [ 123 ].…”

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.

“…Further studies require the creation of biocompatible CNT-based electrodes that can be addressed by adding dialysis bags [89] or by coating with biocompatible polymers (e.g., chitosan, collagen, Nafion®(Chemours, US), and so on) [90]. CNTs have been also successfully tested for a wide range of biomolecules such as DNA [91], immunosensors [92], proteins [93], and other biological molecules. Graphene and CNTs possess high thermal, mechanical, and electronic properties and both materials can be produced on a large scale.…”

Electrochemical biosensors benefit from the simplicity, sensitivity, and rapid response of electroanalytical devices coupled with the selectivity of biorecognition molecules. The implementation of electrochemical biosensors in a clinical analysis can provide a sensitive and rapid response for the analysis of biomarkers, with the most successful being glucose sensors for diabetes patients. This review summarizes recent work on the use of structured materials such as nanoporous metals, graphene, carbon nanotubes, and ordered mesoporous carbon for biosensing applications. We also describe the use of additive manufacturing (AM) and review recent progress and challenges for the use of AM in biosensing applications.

“…Differential pulse voltammetry was employed to measure the signal current response obtained from dissolved Au-Mab-hCG. The developed electrochemical immunosensor shows the linear range of the hCG concentration from 10 pg/mL to 1000 pg/mL, the limit of detection of 5 pg/mL with the sample volume usage as low as 2 µL [167] Furthermore, Wang et al investigated the application of CNTs as a label for highly sensitive electrochemical immunoassays. In this study, CNTs were used to load enzyme markers by covalent interaction of their surface.…”
