Preparation and Application of MOF-Based Electrochemical Sensors for Biomedical Detection

In the field of biomedicine, sensor technology has become an ideal tool for health monitoring and medical services. Electrochemical methods are the most promising candidate technology for the detection due to their simplicity, high sensitivity and specificity. Electrochemical sensors ingeniously combine electrochemical technology with sensor technology. This kind of sensors can achieve efficient and accurate detection. The combination of health monitoring and big data technology poses new requirements for sensors. Achieving high precision, specific identification, and real-time monitoring have become the research directions of electrochemical sensors. Many new functional materials are used to modify electrodes to achieve these functions. Metal-organic frameworks (MOFs) have attracted a lot of attention in the last 20 years because of their special structure which gives them a great range of applications. This porous material helps the electrode capture target molecules, thereby achieving improved sensitivity. In recent years, there are an increasing amount of researches on MOF-based electrochemical sensors. Therefore, this work focuses on the discussion of electrochemical sensors and MOFs. In addition, electrochemical sensors based on MOFs for biomedical detection have also been summarized. This work will promote the application of sensor technology in health monitoring and biomedicine.
