Lab-on-chip cytometry based on magnetoresistive sensors for bacteria detection in milk.Flow cytometers have been optimized for use in portable platforms, where cell separation, identification and counting can be achieved in a compact and modular format.  This feature can be combined with magnetic detection, where magnetoresistive sensors can be integrated within microfluidic channels to detect magnetically labelled cells.  This work describes a platform for in-flow detection of magnetically labelled cells with a magneto-resistive based cell cytometer.  In particular, we present an example for the validation of the platform as a magnetic counter that identifies and quantifies Streptococcus agalactiae in milk.
