Food safety is related to the safety of people's lives and health,as well as human survival and development.The study of analytical and detection techniques for food contaminants has important theoretical and practical implications.In recent years,the application of Molecularly imprinted electrochemical sensors(MIECS)in the field of food detection has gained rapid development.Metal-organic framework materials(MOFs)have received extensive attention as sensor modification sensitizing materials.In this paper,we review the progress of MIECS based on MOFs for food detection.We briefly describe the definition,properties,structure and classification of MOFs,MOF-based composites,MIPs and MOF-MIPS composites.MOFs,MOF/carbon nanomaterials,MOF/metal and metal-oxide nanomaterials,and MOF-MIPS modified electrodes are discussed to improve the performance of molecular imprinted electrochemical sensors.The application of MOFs modified MIECS to the detection of pesticide residues,antibiotics,food additives,and other food safety issues is discussed.The difficulties and challenges faced by MOF-MIPs materials in the sensing domain are analyzed.It is hoped that this paper will be a useful reference and help for researchers in the development and application of MOF sensors.
