The positioning structure that was developed in chapter 5 is now used to position single magnetic particles on top of small TMR sensors. This is the first step to investigate the response of the sensors to single particles.
Many new applications are conceivable with these manipulation and positioning techniques. E.g., by using micro-patterning techniques for biomolecules [100] on a magnetoresistive sensor and applying a magnetic field out of plane to a bound biomolecule on top of the sensor, the sensor can give a force-distance curve for the bond between bead and surface.
