In the Magnetic Systems group at DTU Nanotech, we are developing very sensi­ti­ve magnetic field sensors for use as mag­netic biosensors. Magnetic biosensors rely on the detection of the binding of submicrometer functionalized magnetic beads to the functionalized sensor surface that takes place when the species to be detected is present in the sample.

We are working on all aspects of

-          theory for sensor response to beads

-          theory for sensor design

-          cleanroom sensor fabrication

-          low-noise electrical measurements on sensor arrays

-          development of new detection principles

-          integration of sensors in microfluidic systems

-          biodetection by use of magnetic sensors

There are several project opportunities within the above topics with different weighting between experimental and theoretical work. Examples of project titles are

-          Multisensor set-up with automated switching

-          Investigation of new magnetic stacks for sensors

-          Magnetorelaxometry measurements using a dipstick magnetic sensor
