  • Functional monomers for molecular recognition and catalysis
    Patent number: 7332553
    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.
    Type: Grant

  • Porous, molecularly imprinted polymer and a process for the preparation thereof
    Patent number: 6881804
    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.

  • Molecularly imprinted polymers grafted on solid supports
    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.

  • Reversibly, non-covalent bound surface coating
    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.
