Abstract
The invention relates to a sensor apparatus (100) and a method for detecting clusters with magnetic particles in a sample. The sample is provided in at least one sample chamber (114) of a substantially planar cartridge (110) that is exposed to a modulated magnetic field (Bxz, Byz) generated by a magnetic field generator (190). The sample chamber (114) is illuminated with excitation light (L0), and the resulting output light (Ls) is detected by a light detector (180). The magnetic field (Bxz, Byz) 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 (L0) is focused onto blocking spots (173) behind the sample chamber (114), thus shielding the light detector (180) from direct illumination.
