  • Publication number: 20070106041
    Abstract: The present invention refers to new classes of polymerisable monomers, to molecularly imprinted polymers obtainable by polymerisation of at least one of the monomers and a crosslinking monomer in the presence of a template molecule. The obtained polymers may be used for separation of enantiomers, diastereomers of the template molecule, and also for separation of the template molecule or template molecule analogues from structurally related compounds.

  • Publication number: 20050189291
    Abstract: A porous, molecularly imprinted polymer and a process for its preparation are described. The porous, molecularly imprinted polymer is characterised in that it is obtainable by providing a porous silica; attaching a molecular template to the surface of the porous silica; filling the pores of the porous silica with a polymer; removing the silica and the molecular template, thereby leaving a porous, molecularly imprinted polymer. The process is characterised by the above defined process steps. Also described are a porous polymer vesicle and its preparation with the same features as defined for the porous, molecularly imprinted polymer and its preparation, except for the lack of the molecular template and thus the lack of the molecular imprint in the porous polymer.

  • Publication number: 20050171334
    Abstract: A method of producing a molecularly-imprinted material comprises synthesizing a peptide, oligosaccharide or oligonucleotide on a disposable surface modified support to produce a support surface-attached peptide, oligosaccharide or oligonucleotide, providing a selected monomer mixture, contacting the monomer mixture with the support surface-attached peptide, oligosaccharide or oligonucleotide, initiating polymerisation or at least one crosslinking reaction, dissolving or degrading the support surface-attached peptide, oligosaccharide or oligonucleotide and support, and obtaining molecularly imprinted material.

  • Patent number: 6759488
    Abstract: The invention refers to a molecularly imprinted polymer, a method of preparing a molecularly imprinted polymer material, and the use thereof. According to the invention a support comprising at least one monomer, and a template, in a polymerization medium is polymerized with a free radical initiator, whereafter the template is removed from the molecularly imprinted polymer obtained. The polymerization is confined to the surface of the support, preferably by confining the free radical initiator to the support by bonding adsorption. The molecularly imprinted polymer may be used in chromatography, for separations, in chemical sensors, in molecular recognition as stationary phase in capillaries, in selected sample enrichment or in catalysis.

  • Publication number: 20030166306
    Abstract: The invention relates to a method for the preparation of different molecularly imprinted polzmers for recognition of a target molecule by providing particles, frits or monoliths having initiator confined to the surface thereof in separate compartments, adding different monomer mixtures that may contain a template molecule to each compartment, polymerising said mixtures and finally removing the template and excess monomer(S) from the compartments. The invention also relates to a device containing different molecularly imprinted polymers for recognition of a target molecule.

  • Patent number: 6444321
    Abstract: A surface coating and its use in chemical analysis, electronics, and optoelectronics is disclosed. The surface coating is characterized in that it comprises an amphiphile reversibly bound to a substrate by non-covalent interaction, preferably by polar interaction. The amphiphile is a bolaamphiphile, such as pentamidine.

  • Patent number: 4960762
    Abstract: A chiral two-phase system for resolution of racemic mixtures, or for separation of diastereomers, is disclosed. The system comprises two immiscible liquid phases and one or more enantioselectively binding chiral components, each of which is substantially in one of said phases.Also disclosed is a method for chiral resolution of racemic mixtures, or for separation of diastereomers. Use is here made of the fact that different enantiomers are partitioned differently between the phases in the above-mentioned two-phase system in that one of the enantiomers is selectively bound to one of the chiral components which is substantially in one of said phases.
