Description/Abstract
The use of magnetic beads, for the control of fluid in micro channels is discussed here. The magnetic beads are used to form a plug-like plunger, to control fluid in a micro channel. A theoretical force and water flow rate exerted by the bead plug has been determined. Initial work has shown it is possible to move fluid in a micro channel with volume flow rate of up to 7.2μl min and measurements have been made for the force which a bead lug can exert. The results suggest that this method of fluid control may have applications for a BioMEMS pipette.
