Transition metal Dichalcogenides (TMDs), particularly in their monolayer and ultrathin forms, are emerging as significant materials in quantum sensing due to their distinct quantum attributes. This review delves into the synthesis methods, intrinsic characteristics, and transformative potential of TMDs within quantum sensing technology. Beginning with an overview of TMDs' structural and electronic properties, it covers advanced synthesis techniques vital for achieving high-quality monolayers. Key quantum traits, such as direct band gaps, excitonic behavior, and spin-valley coupling, are analyzed for their applicability in quantum sensing. Despite notable attributes, TMDs face challenges including material stability, scalability, and coherence preservation. The review concludes by examining TMDs' future potential and their anticipated role in advancing next-generation quantum technologies.
