What is it about?
The technique of molecular imprinting consists of the self assembly of a functional monomer and a template molecule in solution followed by co-polymerization of the functional monomer and an excess of an appropriate crosslinking monomer. Removal of the template from the polymer matrix creates vacant recognition sites that enable the polymer to selectively rebind the imprint molecule from a mixture of closely related compounds. After removal of small molecules, the resulting network polymer exhibits significantly higher affinity for the molecules used as the template than for similar molecules, including closely related isomers.

Why is it important?
Cryogels are gel matrix that can be prepared via freezing of polymeric solutions. Because the porosity density and large pores of the cryogels provide large surface area and low flow-resistance, higher adsorption capacities can be achieved and it is possible to study with viscous solution.
Perspectives
The research focused on developing new imprinting materials which have low pressure drop and short residence time for both adsorption and elution, for separation and determination of catechin from red wines. The prepared catechin-MIPs were characterized by both FTIR and SEM and they applied to the clean up of catechins from red wine samples successfully. It can be achieved that the best recovery was obtained for C and the prepared cryogel show good selectivity for target molecule C. It is suggested that the developing catechin-MIP material used as an analytical tool for other potential applications.
