摘要:
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.

摘要:
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.

Molecularly imprinted polymers created with dendrimers or other hyper branched polymer templates provide superior configuration options for the recognition of macromolecules.

The present invention relates to a novel class of water compatible molecularly imprinted polymers (AquaMIPs) capable of selectively binding target molecules such as riboflavin, or analogues thereof, in water or aqueous media, their synthesis and use thereof in food processing and extraction or separation processes.
摘要:
The present invention relates to a method of preparing a molecularly imprinted polymer (MIP), which are used for the recognition of target molecules comprising: co-polymerising at least one functional monomer and at least one cross-linking monomer in the presence of at least one template, wherein oxyanions are used as template and the steric and/or electronic structure of the template is at least partly analogous to the target molecule. The target molecules may be nitro-containing compounds, such as nitroaromatic compounds, or lactones. MIPs selective for explosive nitro-aromatic substances may be produced without handling these hazardous compounds. The invention further relates to a method of determining if a sample contains nitro-containing compounds, such as nitroaromatic compounds, or lactones, MIPs selective for nitro-containing compounds and/or lactones, especially nitro-aromatic compounds and a kit, comprising a molecularly imprinted polymer selective for nitro-aromatic compounds and/or lactones. The invention also relates to use of isosteric and/or isoelectronic oxyanions for the production of MIPs for recognition of nitro-containing compounds, especially nitroaromatic compounds, and lactones.
摘要:
A ball valve assembly for use as a control valve for controlling the flow of gas through a continuous stroke pneumatic tool. The valving element is generally spherical and non-magnetizable. The generally spherical valving element is loosely confined between two concave generally conical surfaces, which are provided on valve seat members. The concave generally conical surfaces are opposed to one another to define a valve chamber therebetween. Sufficient clearance is provided so the generally spherical valving element is free to roll and tumble as it moves in the valve chamber between the concave generally conical surfaces. This allows the ball valve assembly to be self purging of excess lubricant, dust, and the like. Wear is distributed over the entire generally spherical surface of the valving element. The loose confinement is also sufficient to provide a relatively large cross-section of gas passageway through the control valve assembly. The two valve seat members are suitably ported to permit the ball valve assembly to be used as a drop-in replacement for prior pneumatic tool control valves.
