Abstract:	In this work, we demonstrate an impedance approach to detect pathogens bound to magnetic beads. The approach was demonstrated with C-Albicans. We show that when an appropriate frequency is applied to two electrodes present in a microfluidic channel the impedance change in the detection volume can be used to distinguish between unbound beads and beads bound to pathogens. Furthermore, we present a model to relate measured impedance changes to an effective particle diameter.
