Abstract: The present invention relates to a water extraction system for up-concentration of organic solutes comprising a flow cell comprising a membrane; said membrane comprising an active layer comprising immobilized aquaporin water channels and a support layer, and said membrane having a feed side and a non-feed side; and an aqueous source solution in fluid communication with the feed side of the membrane. The system also includes an aqueous source solution in fluid communication with the feed side of the membrane and an aqueous draw solution in fluid communication with the draw side of the membrane. The aqueous source solution comprises the organic solutes. The membrane module comprises an inlet and an outlet for the aqueous draw solution. The aquaporin vesicles are formed by self-assembly of block copolymers in the presence of an aquaporin protein suspension.

Abstract: The present invention relates to a device and a method for clustering and subsequently distributing a plurality of paramagnetic particles in a small volume liquid in a chamber, said chamber having a first wall and an opposite second wall, said method comprising the steps of a) providing a liquid comprising the plurality of paramagnetic particles, b) subjecting the paramagnetic particles to a first magnetic field by means of a first field generating means having first and second mutually spaced opposite poles and defining a first pole axis extending between the poles, the field generating means being arranged relative to the first wall so that the first pole axis (a1) forms an angle (v1) of less than 60° with the first wall, c) moving the magnetic field in a first moving direction having a movement component in the direction of the first pole axis, or, alternatively, changing the polarity of the magnetic field one or more times, and, d) removing the magnetic field.

Abstract: The present invention relates to a device and a method for quantitative detecting of the presence or absence of a target analyte in a liquid sample having a volume of less than 200 ?l, the device comprising a reaction chamber in the form of a capillary channel, a first part comprising a sample inlet for the introduction of a sample containing an analyte, and a discharge outlet for the discharge of waste products; a second part comprising means for detection of the target analyte, and a solution inlet for introduction of washing solutions and reaction mixtures; and means for transferring an immobilized analyte from the first part to the second part of the chamber and vice versa, where the first and second parts are separated such that other liquid sample material may not enter the second part of the chamber and such that light may not be transferred from the first part of the chamber to the detector part of the second part of the chamber.

Abstract: The present invention relates to a device and a method for quantitative detecting of the presence or absence of a target analyte in a liquid sample, the device comprising a reaction chamber having a volume of less than 200 ?l comprising an immobilization matrix capable of capturing the analyte, said immobilization matrix, preferably comprising a particulate magnetic material, having a size distribution that is at least bimodal.
