Metal-Organic Frameworks toward Electrochemical Sensors: Challenges and Opportunities

Owing to their fascinating characteristics, metal-organic frameworks (MOFs) have attracted great attention and been utilized in a range of applications. The use of MOFs in electrochemical sensors has become an emerging subfield since 2013. However, the poor chemical stability in aqueous solutions and low electrical conductivity of most MOFs become two main concerns that hinder the use of pristine MOFs in electroanalytical systems. In this short review, we aim to focus on these issues and provide perspectives regarding the opportunities and possible strategies in future studies to overcome these challenges in order to design the MOF-based electrochemical sensors.
