With the rapid development of technology, electrochemical sensors have been widely applied in fields such as disease diagnosis, environmental monitoring, and food safety due to their high sensitivity, good selectivity, low cost, and simple operation. Although traditional sensing materials (such as noble metals, carbon-based materials, or conductive polymers) have made remarkable progress, their limited active site density, low porosity, and non-tunable electronic structures restrict their detection performance in complex systems. In recent years, electrically conductive metal-organic frameworks (EC-MOFs) have offered brand-new research opportunities and development directions for the field of electrochemical sensing. This is attributed to their high specific surface area, abundant pore structure, flexible tunable design characteristics, as well as excellent catalytic performance, efficient electron transport capability, and significant signal amplification effect. This review systematically summarizes the latest research progress of EC-MOFs materials in the field of electrochemical sensing, focusing on the design and synthesis strategies of working electrodes for EC-MOFs-based electrochemical sensors, including in-situ synthesis, ex-situ synthesis, and combined in-situ and ex-situ strategies. Additionally, it provides a detailed review of their breakthrough applications in biomolecular recognition, environmental pollutant monitoring, etc. Meanwhile, the review provides a deep analysis of the key challenges faced by EC-MOFs in the field of electrochemical sensing and outlines their future development directions.
