MoS2 quantum dots and their diverse sensing applications

Abstract

Molybdenum disulfide (MoS2) quantum dots (QDs) are a type of nanomaterial with unique electronic and optical properties. This abstract explores how these dots are made and what they look like, and how they can be used in different kinds of sensing platforms. The review covers their use in gas sensing, biosensing, and environmental monitoring, and explains how MoS2 QDs are particularly good at detecting things with high sensitivity and selectivity. By integrating these nanomaterials into sensing devices, we can create new and more effective sensing technologies that can be used in a variety of fields. In addition to their sensing capabilities, MoS2 QDs have other advantages too, like being easy to modify, having a stable structure, and being able to change their bandgap. All these things make MoS2 QDs adaptable to different sensing platforms, which means they can perform well even in challenging environments. This abstract goes into more detail about the different ways MoS2 QDs can be made, how we can study them, and what new developments are happening in the world of sensing technologies. We will also talk about what challenges there are and what the future of MoS2 QDs might look like. MoS2, when reduced to a nanoscale, exhibits various applications in the quantum and electronic fields. It is available with both covalent and Van der Waals bonding, allowing MoS2 to be utilized in an optimal way for sensing different gases. However, studies related to the sensing characteristics of MoS2 are currently insufficient in fields such as optoelectronics, hydrogen testing and evolution, biomedicines, and IOT-based areas. Nevertheless, MoS2 can be introduced harmlessly into internal organs as it does not undergo any harmful biological interaction. These numerous features of MoS2 make it ideal for use in various sensing approaches.
