Abstract
A sensor device (15) for detecting magnetic particles (13) has a binding surface (40) with binding sites thereon and includes at least one sensor element (23) for detecting the presence of magnetic particles (13), an element or elements for attracting magnetic structures having at least one magnetic particle (13) toward and onto the binding surface (40) of the sensor device (15), and an element or elements for re-arranging and randomizing the position of individual magnetic particles (13) with respect to the binding sites on the binding surface (40) to give binding sites on all individual particles (13) a substantial probability to have a contact time with binding sites on the binding surface (40). With such sensor device (15), the speed of detection of target molecules in a fluid is enhanced.
