Abstract:
1. A method of obtaining a water compatible molecularly imprinted polymer, comprising the steps: (a) providing a target or a template, or a structural analogue thereof, (b) providing one or more selected functional monomer(s) and one or more selected crosslinking agent(s), in a suitable polymerisation medium or solvent containing a selected free radical initiator, (c) copolymerising said functional monomer(s) and said crosslinking agent(s) in the presence of said target, template or structural analogue in said polymerisation medium, (d) removing said target, template or structural analogue by solvent extraction or by photochemical means, (e) obtaining a molecularly imprinted polymer (AquaMIP), wherein hydrophilic comonomer(s), different from the functional monomer, are provided with the functional monomer, and/or said crosslinking agent(s) is hydrophilic; and (f) post-modifying, by hydrolysis, said water compatible molecularly imprinted polymer in order to reduce the non-specific hydrophobic binding.
