The dimers are first formed by using a eternal magnetic field to mix up the sample. After all dimers are formed, a laser light is shone upon the sample while a rotating magnetic field is applied. This causes the dimers to rotate and scatter light differently depending on how the magnetic field is located relative to them. This scattered light is picked up with a photodiode that is positioned at 90 degrees from the laser. The dimer rotation frequency is then calculated by using a fast fourier transform.

A user interface is made where users can log into their own account, where they can see previous measurements, adjust settings for the magnet and send results via email. This is done through a touchscreen on the biosensor.
