        abstract = {The planar Hall effect (PHE) magnetic bead array countermicrochip integrating 24 of single sensors based on a simple NiFe/IrMn bilayer structure with a patterned size of 3{$\times$}3 {\ensuremath{\mu}}m2 has been fabricated and characterized. Single PHE sensors exhibit a sensitivity of about 2.5 m?/Oe. It was well applied for single Dynabeads? M-280 detection, where one bead can induce a signal change, {\ensuremath{\Delta}}V{$\sim$}2.2 mV, under the applied magnetic field of 20 Oe and a sensing current of 2 mA. This type of microchip is promising for quickly detecting and identifying multiple biological agents in the environment.}
