MXene quantum dots (MQDs) are a burgeoning novel material that stands out for its excellent physicochemical properties. It is especially effective in serving as biosensing materials. It can be utilized as a biomarker for health conditions or as a marker for remnant chemical composites. Recently, there have been a great deal of advancements in the development of MGDs. It is requisite to recapitulate the progress achieved, providing a systematic summary of recent developments. This paper systematically reviews the latest applications of MQDs in biosensing. MQDs are used to detect metabolites and disease biomarkers through electrochemical, conventional fluorescent, and ratiometric fluorescent strategies, enabling sensitive detection of all sorts of biomarkers. In addition, MQD-based fluorescent and ratiometric fluorescent sensors are applied to monitor environmental pollutants and food contaminants. Modification strategies, including elemental doping, noble metal loading, and nanocomposite superposition, significantly improve the sensitivity and selectivity of sensors. Despite remarkable progress, challenges including large-scale synthesis, biocompatibility, and device portability still exist. Refinement can be made, such as optimizing preparation methods, enhancing biocompatibility, and promoting clinical transformation. This review offers a thorough reference for the design and future development of MQD-based biosensors.
