Abstract:
The invention comprises a polymeric microarray support (1) for an optical assay arrangement (2) comprising optical means (3, 4, 6) for detection of light emitted from the support. The microarray support is provided with microfeatures comprising a surface enlarging pattern (5), i.e. grooves having a selected depth (8). The depth is selected such that the sum of the depth and of the variations in the thickness (7) of the support substantially corresponds to the depth of focus of the optical means.

The method comprising the steps of providing a positive lower half of a mould (10) having protrusions (12) defining the size and shape of the said miniature nozzle, in which the protrusion mate with the holes of the stable base plate, and inserting the stable base plate in the mould, closing the mould with a lid (16) and applying a curable polymer (18) to the mould and exposing the curable resin to curing conditions. A nozzle plate structure (20) made according to the method is also disclosed.
Abstract:
Multilayer microscale fluid handling device that comprises at least one polymer substrate (30) with a microscale fluidic structure formed in a first surface of the substrate, and a microscale through-hole that extends from the microscale fluidic structure to an opposite surface of the substrate. There is also provided a method for manufacturing such.
Abstract:
The present invention is directed to a lateral flow assay device for the monitoring and measuring of coagulation and method thereof. Ideally, the invention is directed to a lateral capillary flow device for the monitoring and/or measurement of coagulation in a liquid sample wherein the device comprises a non-porous substrate with a zone for receiving a sample and a defined flow path zone wherein a clotting agent is deposited on at least part of the defined flow path zone to accelerate the coagulation of the liquid sample, enable the formation of an evenly distributed clot along the defined flow path zone and to result in the change in flow rate or cessation of flow of the liquid sample along the defined flow path zone.
Abstract:
A nozzle chip (3') for ejecting a liquid such as in an electrospray device is built from a substrate chip having grooves (5, 7) on a top surface. A lid (25) is attached to the top surface closing the grooves to form channels one of which has an open outlet end (9). At the outlet end a nozzle is formed at or attached and it has an outlet opening from which the liquid is to be ejected. Alignment recesses (13, 15) are made at edges of the substrate chip and they are accurately positioned in relation to the outlet opening, the alignment recesses allowing an accurate mounting of nozzle chip giving the outlet opening of the nozzle a reproducible position in the device where it is to be used. At the outlet end a recess (17) in the substrate chip can be provided and the nozzle can then be located in the recess to mechanically protect it.
Abstract:
Objects, such as molecules, macormolecules, nanoparticles, cells and organelles are immobilised to a surface by covalent bonds and in a site-specific manner using an external source of energy, acting on the surface in the presence of said objects, when said surface and said objects have been chemically derivatised to present groups capable of forming reactive moieties when subjected to said source of energy. The exact location of the immobilisation is determined either by exposing the surface to said source of energy in a highly localised manner, or by creating site-specific defects or a pattern, to which groups capable of forming reactive moieties when subjected to said source of energy are first arranged. Said pattern may be in the form of electrodes, arranged on the surface.
