MXene is a novel 2D material that has good electrical, optical, and chemical properties. MXenes have a rich functional group, surface morphology like graphene, and their high hydrophilicity properties have attracted their use in the field of biosensors, photocatalysis, areas of energy, and electromagnetic shielding. MXene has an excellent fast electron transportation property which is used in electrochemical-based sensor applications, and it has a good optical property which is used in fluorescence-based sensor applications. In this review, we discussed the electrochemical, calorimetric, and fluorescence-based sensor applications for the detection of some basic analytes such as hydrogen peroxide, glucose, metal ions, pesticides, and some other biomolecules. Herein, we have collectively addressed the recent developments of the MXene based electrode material for sensor applications.
