Combining positive and negative magnetophoreses to separate particles of different magnetic properties
A new separation method that combines both positive and negative magnetophoreses based on ferrofluids is used to separate mixtures of particles with different magnetic properties. Ferrofluids are stable magnet...

Three-dimensional and analytical modeling of microfluidic particle transport in magnetic fluids
We present an analytical model that can predict the three-dimensional (3D) transport of non-magnetic particles in magnetic fluids inside a microfluidic channel coupled with permanent magnets. The magnets produ...

Continuous-flow ferrohydrodynamic sorting of particles and cells in microfluidic devices
A new sorting scheme based on ferrofluid hydrodynamics (ferrohydrodynamics) was used to separate mixtures of particles and live cells simultaneously. Two species of cells, including Escherichia coli and Saccharom...

Focusing microparticles in a microfluidic channel with ferrofluids
We report a novel on-chip microparticles focusing technique using stable magnetic nanoparticles suspension (i.e., ferrofluids). The principle of focusing is based on magnetic buoyancy forces exerted on non-mag...

Analytical model of microfluidic transport of non-magnetic particles in ferrofluids under the influence of a permanent magnet
This study describes an analytical model and experimental verifications of transport of non-magnetic spherical microparticles in ferrofluids in a microfluidic system that consists of a microchannel and a perma...

Continuous separation of non-magnetic particles inside ferrofluids
We present a novel and label-free continuous flow non-magnetic microparticle separation scheme in a microfluidic device under static magnetic fields. The separation process is conducted inside water-based ferr...
