Molecularly imprinted polymers for electrochemical detection and analysis: progress and perspectives

The molecularly imprinted polymers (MIPs) are a kind of polymers formed by the size, shape and specific functional groups of the template molecule. MIPs are widely used in various fields, especially in molecularly imprinted electrochemical sensors (MIECS) due to their unique structure and specific recognition capability. In this review, we systematically summarize the recent advances of MIECS reported in recent years for the detection of organic compounds, metal ions, emerging pollutants and biomolecules. We focus on the preparation, structures and components of sensing systems, and demonstrate the improvement of detection performances such as sensitivity and selectivity. Finally, the rational summaries, present challenges and future prospects in the field of MIECS have been discussed reasonably.
