Magnetophoretic cell clarification
… more effectively. The governing equations for magnetophoretic clarification were applied to the quadrupole configuration to predict particle trajectories through the column and to predict the separation efficiency under different flow conditions, which showed a good match to the experimental …

Microfabricated magnetophoretic focusing systems for the separation of submicrometer particles
Magnetic separation is an actively researched field due to its broad applicability to the mineral, chemical, and biological industries. The objective of this work was to design, fabricate, and test systems to study magnetophoresis of particles in suspension. To achieve this goal, two system …

Magnetophoretic focusing on submicron particles dispersed in a polymer-stabilized magnetic fluid
… overall goal of this work was to investigate the magnetophoretic focusing of non-magnetic particles suspended in magnetic fluids, which are colloidal suspensions of nano-sized magnetic particles. With the magnetic fluid as the solvent, dispersed non-magnetic particles behave as if they were …

Physical Properties of Macromolecule-metal oxide nanoparticle complexes: Magnetophoretic Mobility, Size, and Interparticle Potentials
Magnetic nanoparticles coated with polymers hold great promise as materials for applications in biotechnology. In this body of work, magnetic fluids for the treatment of retinal detachment are examined closely in three regimes; motion of ferrofluid droplets in aqueous media, size analysis of the …

Magnetomicrofluidics Circuits for Organizing Bioparticle Arrays
… into an array in a controlled manner.</p><p>My magnetophoretic circuits use passive elements constructed in patterned magnetic thin films to move cells along programmed tracks with an external rotating magnetic field. Cell motion along these tracks is analogous to the motion of charges in an …

Native chromatin extraction and its structure analysis
… order to analyze the CARs, we also developed a magnetophoretic chromatography method to remove the free RNAs, and the CARs were further extracted from the collected chromatin. The extracted CARs were reverse transcribed as cDNA and further characterized by real-time qPCR. The total assay time …

Biophysical Techniques of Transcutaneous Drug Sampling and Drug Delivery
… and magnetically enhanced partition coefficient. Magnetophoretic patch system was designed and pharmacokinetic studies were performed. Magnetophoresis resulted in higher dermal bioavailability of drugs compared to passive transdermal drug delivery. It was also found from the in vitro studies that …

Size based separation of submicron nonmagnetic particles through magnetophoresis in structured obstacle arrays
… particles in the submicron size range utilizing magnetophoretic forces. When a nonmagnetic particle is immersed in a magnetic fluid and subjected to magnetic field gradients, it behaves like a magnetic hole and experiences magnetic buoyancy forces proportional to its volume. This size dependence …

Magnetorheological fluids for extreme environments : stronger, lighter, hotter
… governed by a balance between hydrodynamic and magnetophoretic forces. Finally, the flow of MR fluids in spatially-inhomogeneous magnetic and deformation fields was studied. A slit-flow magnetorheometer was manufactured to measure the bulk MR response of the fluid under non-uniform fields. In …

Physical Properties of Magnetic Macromolecule-Metal and Macromolecule-Metal Oxide Nanoparticle Complexes
… nanoparticles (nanorods) have an increased magnetophoretic mobility over spherical magnetic nanoparticles with the same equatorial radius. This property makes them attractive candidates for in vivo biological applications. Anisotropic mixed ferrite nanoparticles were coated with a …

Investigation on the Mechanism of Electrocodeposition and the Structure-Properties Correlation of Nickel Nanocomposites
… explained by the interplay of Lorentz force and magnetophoretic force. The structure and the properties of the nickel matrix were significantly altered due to the codeposition of nanoparticles. The pure nickel deposits from the sulfamate bath exhibited a strong <100> texture, and those from …
