Abstract: A lateral flow test system having an optical reader, a lateral flow cartridge and a computer system is provided. The lateral flow cartridge includes a porous test strip with a reading window into the porous test strip exposing an exposed zone of the porous strip. The optical reader has a reader housing and a slot for inserting the cartridge into the reader housing. The optical reader has an illumination arrangement adapted for illuminating the exposed zone of the porous strip when the cartridge is inserted into the slot. The optical reader further has a video camera configured for acquiring a series of digital images comprising the exposed zone of the porous strip. The computer system receives sets of pixel data representing the plurality of consecutive digital images and calculates wetting progress along the length of the exposed zone of the porous strip based on the sets of pixels data.

Abstract: A nucleic acid probe, a method of immobilizing the nucleic acid probe to a solid support and the solid support including the immobilized probes using UV light. The nucleic acid probe includes a terminus anchor chain portion, and a capture portion wherein the terminus anchor chain portion includes a sequence of at least 18 nucleotides composed of stretches of up to 5 nucleotides of base type X with intermediate nucleotide(s) of base type Cytosine (C) and optionally one nucleotide of base type Guanine (G) or a sequence with at least 90% similarity thereto, wherein each base type X independently of each other designate base type Thymine (T) or base type Uracil (U).

Abstract: The invention provides a microfluidic device for mixing liquid reagents, the device comprises, a chip forming at least one reaction chamber between a bottom and a top and extending between an inlet and an outlet. To enable manufacturing from less rigid materials, the device comprises pillars extending from the bottom to the top. The invention further provides a method of mixing reagents by use of the device.

Abstract: The invention provides a microfluidic device for macromolecule amplification by sequential addition of liquid reagents. The device of the invention comprises a chip forming a plurality of reaction chambers each extending between an inlet and an outlet, each inlet being in fluid communication with a common junction via micro channels. To enable amplification of DNA, e.g. by MDA, the device comprises a diffusion barrier at each inlet configured to increase the pressure threshold for a reagent to cross the resistor. The invention further provides a method of mixing liquid reagents by use of the device where single DNA molecules are allowed to cross the diffusion barrier individually.
