ABSTRACT
MXenes are two-dimensional (2D) layered nanomaterials that have newly been created and have a unique potential for bioanalytical applications. They possess good metallic conductivity, ion transportation, low diffusion barrier, and are easy to tune the surface structure. MXenes are transition metal nitrides, carbonatites, or carbides, with the empirical formula Mn+1Xn, where X is carbon and/or nitrogen while M stands for an early transition metal. MXenes have drawn attention because of their unusual properties in industries such as clean energy, electronics, fuel cells, supercapacitors, and catalysis. MXenes are appealing for biosensing applications due to their composition and layered structure. MXenes have high conductivity and layered texture, they can be utilized in the construction of biosensors. These characteristics can be applied to a broad range of biosensing systems and applications. MXene-integrated conducting polymers (MXCP) in the construction of composite materials are the latest advancements for wearable electronics and are summarized in this paper. The use of MXCP in sensors and bioelectronics is described in detail and also this chapter discusses the significant progress in the creation of electrochemical and biosensors using MXenes, as well as future demands and prospects in this discipline.
