Samenvatting

This paper reports various ways of field-based manipulation of magnetic colloidal particles to enhance biochemical reactions in lab-on-chip systems [1]. For one (I), we show the possibility to assemble the suspended magnetic micro-particles as tunable re-formable micro-stirrers capable of performing enhanced micro-scale mixing and biochemical-assays. Secondly, we show that (II) magnetically-induced clusters and aggregates of magnetic micro-particles can be dis-assembled (within 1 minute) into individual entities using time-varying magnetic fields. Lastly, we show (III) that very strong vortical fluid flows (1 mm/s) can be induced by a so-called swarm of magnetic particle chains, resulting in an en-hancement of biochemical capture kinetics.
