Document Summary: This review explores the integration of molecularly imprinted polymers (MIPs) with piezoelectric biosensors for the quantitative detection of small molecules. MIPs offer a robust, stable, and cost-effective alternative to traditional biological recognition elements, providing a synthetic supra-molecular approach to molecular recognition. The document discusses the principles of piezoelectric sensing, particularly quartz crystal microbalances (QCMs), and details various methods for synthesizing and incorporating MIPs into these sensor platforms. It highlights the advantages of MIPs, such as their long shelf life and ability to withstand harsh conditions, and reviews their application in diverse areas including environmental monitoring, clinical diagnosis, and enantiomeric separation. The review also addresses challenges related to selectivity and the development of portable devices for real-world sample analysis.
