Transition Metal Dichalcogenides for Sensing and Oncotherapy: Status, Challenges, and Perspective

Abstract Transition metal dichalcogenides (TMDCs) are increasingly being used for chemical sensing, biosensing, and tumor therapy on account of their diversity, biocompatibility, multifunctionality, adjustable bandgap, and excellent photoelectric characteristics. This review mainly discusses the effect of the elemental composition and structure of TMDCs on the performance of electrochemical, biofluorescence, and colorimetric biosensors. The applications of TMDCs in tumor therapies are reviewed here. Furthermore, the current challenges and future directions for developing TMDC‐based theranostics are summarized.
