Abstract
The invention relates to a sensor apparatus () and a method for detecting clusters with magnetic particles in a sample. The sample is provided in at least one sample chamber () of a substantially planar cartridge () that is exposed to a modulated magnetic field (B, B) generated by a magnetic field generator (). The sample chamber () is illuminated with excitation light (L), and the resulting output light (L) is detected by a light detector (). The magnetic field (B, B) may particularly rotate, inducing a corresponding rotation of clusters which in turn induces a variation of the detection signal (S). According to a preferred embodiment, excitation light (L) is focused onto blocking spots () behind the sample chamber (), thus shielding the light detector () from direct illumination.
