Single-atom materials (SAMs) feature isolated metal sites embedded inside inorganic or organic supports. Thanks to the well-defined electrochemically active centers, SAMs have demonstrated expectational performance as electrochemical sensors. In this review, we provided an introductive discussion on the current research progress of metal-inorganic/organic SAMs-based sensors, including mainly metal-carbon, metal-metal oxide/hydroxide/dichalcogenide, metal-organic frameworks, and metal-doped covalent organic frameworks. Following these examples, we outlined a few general strategies for rationalizing SAMs towards better sensitivity, selectivity, and stability.
