title = "A phase change microvalve using a meltable magnetic material: Ferro-Wax",
abstract = "This paper presents a novel phase change microvalve using a paraffin-based ferrofluid plug (called {"}Ferro-Wax{"}). The Ferro-Wax plug is essentially leak-proof because of the phase change nature of the material; once the plug is solidified, it forms a solid seal. The meltable magnetic plug changes the phase from solid to liquid by an on-chip heating and moves remotely in a channel by a magnetic actuation. The reversible microvalve performed excellently up to 50 psi. The ease of fabrication and integration makes this microvalve invaluable for a next generation lab-on-a-chip device for on-chip sample preparation and label-free detection, which is currently underway.",
