摘要： A method and apparatus for extracting magnetic particles from a sample includes placing the sample near a liquid carrier, which is immiscible with it, in a configuration stable under the influence of gravity. The magnetic particles are moved by a magnetic field from the sample and into the carrier. The magnetic particles are non-wetting with respect to the carrier and will therefore form agglomerates in the carrier.

摘要： A system for detecting a plurality of analytes in a sample includes an aperture array and a lens array for generating and focusing a plurality of excitation sub-beams on different sub-regions of a substrate. These sub-regions can be provided with different binding sites for binding different analytes in the sample. By detecting the different luminescent responses in a detector, the presence or amount of different analytes can be determined simultaneously. Alternatively or in addition, collection of the luminescence radiation can be performed using the lens array for directly collecting the luminescence response and for guiding the collected luminescence response to corresponding apertures. The excitation sub-beams may be focused at the side of the substrate opposite of the lens array, and an immersion fluid is provided between the lens array and the substrate to increase the collection efficiency of the luminescence radiation.

摘要： A sensor is described for use with at least one optical detector (5), the sensor comprising a substrate (11) with optical outlets, a porous membrane (12) and micro fluidic channels (13) for conducting analyte fluid towards sensing locations (10) of the porous membrane (12). The sensing locations (10) are adapted for at least restraining light variable molecules (23) which bind to analytes to be determined. The optical output of the light variable molecules changes when they are in close proximity to a target molecule. The micro fluidic channels (13) are shaped to reflect light emitted from the sensing locations (10) towards the optical outlets and the substrate has diffracting optical elements (15) aligned with microfluidic channels to diffract light towards the optical outlets. The diffracting optical elements can be lenses.
