Abstract
The present invention relates to a magnetoresistive sensing device, a system and a method for determining a density of magnetic particles in a fluid. The magnetoresistive sensing device has a substrate () with a layer structure () for supporting a fluid (). The layer structure has a first surface area () in a first level and a second surface area () in another second level and a magnetoresistive element () for detecting the magnetic field of at least one magnetic particle () in the fluid, the magnetoresistive element being positioned near a transition () between the first and second surface area and facing at least one of the surface areas. A corresponding system and method is described as well.
