Molybdenum Disulfide-Based Nanoprobes: Preparation and Sensing Application.

The use of nanoprobes in sensors is a popular way to amplify their analytical performance. Coupled with two-dimensional nanomaterials, nanoprobes have been widely used to construct fluorescence, electrochemical, electrochemiluminescence (ECL), colorimetric, surface enhanced Raman scattering (SERS) and surface plasmon resonance (SPR) sensors for target molecules' detection due to their extraordinary signal amplification effect. The MoS nanosheet is an emerging layered nanomaterial with excellent chemical and physical properties, which has been considered as an ideal supporting substrate to design nanoprobes for the construction of sensors. Herein, the development and application of molybdenum disulfide (MoS)-based nanoprobes is reviewed. First, the preparation principle of MoS-based nanoprobes was introduced. Second, the sensing application of MoS-based nanoprobes was summarized. Finally, the prospect and challenge of MoS-based nanoprobes in future were discussed.
