Fluid Dispensing using Superparamagnetic Beads
Husband, B, Evans, AGR and Melvin, T (2005) Fluid Dispensing using Superparamagnetic Beads. At 16th MicroMechanics Europe Workshop, MME, Gothenburg, Sweden, 04 - 06 Sep 2005. , 338-341.
The aim of this investigation is to produce an injection device for precise dispensing of nanolitre volumes of fluid using a piston formed from superparamagnetic beads. A plug of Fe2O3 beads is formed by applying a non-uniform magnetic field from a bullet magnet within close proximity to the fluid filled channel containing the beads. Once the plug is formed it can be moved through the micro channel by moving the magnet and thus, provide a plunger-like action. Fluid is displaced by moving the magnetic plug, providing a technique for fluid dispensing.
