Abstract

A device and a method are disclosed for the detection and/or for the quantification of an analyte. In at least one embodiment, the device includes a basic matrix and magnetized nanoparticles, which are arranged in moveable fashion in or at the basic matrix and to which catcher molecules that bind specifically to the analyte are anchored. Further, the mobility of the nanoparticle in the basic matrix can be influenced by a binding of the analyte to be detected to the catcher molecules and can be read out magnetically.
