Problems solved by technology

The setup of the micropump in the device is difficult to manufacture, very expensive, and prone to failure
Using device 1 with micropumps, a large amount of stationary fluid is produced, which means that a considerable amount of fluid cannot withstand analysis
Therefore, a large amount of fluid including the target is required, which creates disadvantages in terms of cost, time and sample extraction

Embodiment Construction

[0031] figure 1 A diagram showing the state of a prior art device 1 for analyzing substances, essentially fluids 3 originating from the human or animal body, eg blood, saliva, urine. Therefore, below the term "substance" is replaced by the term "fluid 3". The fluid 3 comprises objects 30a, 30b to be analyzed. The term "microfluidic device" is by definition included in the term "device 1". The device 1 comprises a housing comprising a chamber 23 for containing a fluid 3 . Inside the chamber 23 , a barrier 25 protrudes across the entire height of the device 1 , thereby providing a conduit 26 in the chamber 23 enabling a fluid to circulate. The device 1 has an inlet 22 for allowing the fluid 3 to reach a chamber 23 within the device 1 . A micropump 24 is provided in the device 1 for applying pressure to the fluid 3 so that the fluid 3 circulates around the barrier 25 in the device 1 . The micropump 24 continues to pump the fluid 3 through the device 1 along and around the ba...

Abstract

It is an object of the invention to provide for an alternative for analyzing fluids. To this end a device for analyzing fluids comprising magnetic particles is provided, the device comprising magnetic means for generating a magnetic field designed for exerting a magnetic force to the magnetic particles creating a movement of the fluid comprising targets and a membrane with an array for moving the fluid through or along the array.

Description

technical field [0001] The invention relates to a device for analyzing a fluid, a control device for guiding magnetic particles and a fluid through different parts of a membrane of the device, and a method for analyzing a fluid. Background technique [0002] In order to detect so-called objects in various fluids, devices have gradually been developed for different applications. As examples of targets there are nucleic acids, antibodies, antigens, receptors, haptens or ligands. The device is suitable for detecting additional targets such as cell fragments, viruses or substances within food fragments. Targets are usually molecules, in which case they are also called molecular species. As examples of fluids including objects, there are blood, saliva, urine, tissue extracts, interstitial fluids, food extracts, and environmental samples. Additional fluids comprising objects to be detected are also suitable. The fluid can be extracted directly from the source without treatment...
