Abstract
A method of detecting a biological sample includes the following steps. A magnetic sensor chip is provided, wherein the magnetic sensor chip includes a substrate and a magnetic sensing layer located on the substrate. Probes are connected to the magnetic sensor chip. A sample solution containing biological samples labeled with a first marker is provided on the magnetic sensor chip, so that the biological samples labeled with the first marker are hybridized with the probes. Magnetic beads labeled with a second marker are provided on the magnetic sensor chip, so that the magnetic beads labeled with the second marker are bound onto the biological samples labeled with the first marker. A signal sensed by the magnetic sensing layer is detected by a magnetic sensor.
