Single magnetic particle dynamics in a microchannel

Single magnetic particle dynamics in a microchannel

Functionalized magnetic particles are used in micrototal analysis systems since they act as magnetically steered mobile substrates in microfluidic channels, and can be collected for bioanalytical processing. Here, we examine the motion of magnetic microbeads in a microfluidic flow under the influence of a nonuniform external magnetic field and characterize their collection in terms of the magne...

Fluctuation dynamics of a single magnetic chain.

‘‘Tunable’’ fluids such as magnetorheological ~MR! and electrorheological ~ER! fluids are comprised of paramagnetic or dielectric particles suspended in a low-viscosity liquid. Upon the application of a magnetic or electric field, these fluids display a dramatic, reversible, and rapid increase of the viscosity. This change in viscosity can, in fact, be tuned by varying the applied field, hence ...

Low-frequency excitations in a molecular glass: Single-particle dynamics.

The low-frequency dynamics of a molecular glass former has been investigated by means of inelastic neutron scattering &om a mostly incoherent sample as well as by computer molecular-dynamics simulation. The mode assignments have been carried out using the neutron data for the polycrystal as well as by means of the analysis of the density of states (DOS) computed from a lattice-dynamics calculat...
