| Title: | MICROELECTRONIC SENSOR DEVICE FOR CONCENTRATION MEASUREMENTS | |||||||||||
| Abstract: | The invention relates to a method and a magnetic sensor device for the determination of the concentration of target particles (2) in a sample fluid, wherein the amount of the target particles (2) in a sensitive region (14) is observed by sampling measurement signals with associated sensor units (10a-10d). The target particles (2) may optionally be bound to binding sites (3) in the sensitive region, and a parametric binding curve, e.g. a Langmuir isotherm, may be fitted to the sampled measurement signals to determine the desired particle concentration in the sample. Moreover, parameters like the sampling rate and the size of the sensitive region (14) can be dynamically fitted during the ongoing sampling process to improve the signal-to-noise ratio. In another embodiment of the invention, single events corresponding to the movement of target particles into, out of, or within the sensitive region are detected and counted. | |||||||||||
