Ferrofluid mediated nanocytometry
Lab Chip, 2012We present a low-cost, flow-through nanocytometer that utilizes a colloidal suspension of non-functionalized magnetic nanoparticles for label-free manipulation and separation of microparticles. Our size-based separation is mediated by angular momentum transfer from magnetically excited ferrofluid particles to microparticles.

Structural transformations in ferrofluids
Physical Review E, 2003We present results of theoretical study of internal structural transformations in magnetic liquids consisting of identical spherical magnetic particles suspended in a carrier liquid. As the results show, when the dimensionless characteristic energy of magnetic interaction epsilon between particles is less than a certain critical value epsilon('), the ...

Applied Optics, 2006
A magnetic liquid mirror based on ferrofluids was demonstrated. Magnetic liquid mirrors represent a major departure from solid mirror technology. They present both advantages and disadvantages with respect to established technologies. Stroke (from a fraction of a wave to several hundreds of micrometers), cost (a few dollars per actuator), and ...

A Novel Ferrofluidic Inclinometer
IEEE Transactions on Instrumentation and Measurement, 2007Inertial transducers based on the use of ferrofluids as inertial mass can be of great interest due to their peculiarities and due to the advantages that they show when compared to traditional devices. Ferrofluids are special solutions of magnetic particles in a carrier liquid whose density and other physical features can be controlled by an external ...

Transport properties of ferrofluids
Physical Review E, 2003Long-time self-diffusion coefficients of ferrofluid suspensions are derived from an effective Langevin equation approach. The dependences of these transport properties on the volume fraction of particles and the strength of interparticle interaction are investigated.

Journal of Magnetism and Magnetic Materials, 1990
We have incorporated magnetic particles of sizes 100 Å in swollen lamellar phases. It is the first time, to our knowledge, that solid grains are stabilized in ordered liquid phases. Moreover, when the grains are magnetic, this composite system realizes a periodic packing of a bidimensional magnetic liquid alternating with a non-magnetic fluid, and ...

La Radiologia medica, 1987
Ferrofluids are colloidal suspensions of extremely small ferromagnetic particles, the physical properties of which belong to a very complex chapter of modern magnetohydro-dynamics. Because of that, ferrofluids will possibly open new perspectives of medical applications, both in diagnostic radiology and therapeutic oncology.

Since the first preparation of ferrofluids in the mids of the 60s the understanding of their behavior is a matter of both theoretical and experimental research. Especially the interaction of rheological and magnetic properties (known as the magnetoviscous effect) is a main concern for being the source of the unique behavior of ferrofluids.
