Abstract
We report on the measurement of the Browinan relaxation frequency of a magnetic nanobeads suspension in microfluidic system using a novel magneto-optical method. We demonstrate that by lock-in analysis of the signal produced on a photodetector by the light transmitted through the particle suspension excited by an uniaxial AC magnetic field, it is possible to precisely record the frequency response of commercial magnetic nanobeads in a microfluidic channel.
