Abstract:
1. A method for determining whether an analyte is present in a sample, the method comprising: (a) contacting a magnetic sensor device with a set of samples contained in a set of fluid reservoirs to generate a signal from the magnetic sensor device, the magnetic sensor device comprising a support with two or more elongated regions each having a magnetic sensor array comprising one or more magnetic sensor selected from the group consisting of a spin valve detector and a magnetic tunnel junction detect disposed at a distal end of the elongated region, wherein one or more magnetic sensor has an analyte-specific probe bound to a surface of the magnetic sensor; and (b) determining with a signal processing unit whether the analyte is present in each sample based on the signal from the magnetic sensor device, wherein the determining comprises receiving the signal from the magnetic sensor device and processing the signal to obtain a result of whether the analyte is present in each sample.
