Abstract: Actuation principles of superparamagnetic beads applicable on biosensing (at single beads and chain orderning) are studied in this report. This research can be used to develop new techniques that are able to accelerate bio-assays. An experimental setup containing a sub-microliter fluid volume surrounded by four miniaturized electromagnets is designed and fabricated. On the basis of velocity measurements, the induced bead behaviour has been compared to theoretical models.
