[Progress in application of molecularly imprinted polymers based on β-cyclodextrin to environmental and food sample pretreatment].

β -cyclodextrin (β-CD) and its derivatives are an emerging class of functional monomers that find widespread use in molecular imprinting. It is well known that β-CD and its derivatives are capable of forming host-guest interaction inclusion complexes with many guest molecules. Molecularly imprinted polymers prepared via this type of interaction have the advantages of high stability and excellent selectivity. Therefore, β-CD-based molecularly imprinted polymers have attracted much attention and have been extensively developed for the selective separation and enrichment of target compounds in environmental and food samples with complex matrices. The objective of this review is to reveal the advantages of such molecularly imprinted polymers in complex sample pretreatment by reviewing the applications of molecularly imprinted polymers based on β-CD and its derivatives as functional monomers in environmental and food sample pretreatment since 2013.
