Static Magnetic Field Effects on Cells: A Possible Road to Cell Differentiation

Prina-Mello A., Campbell V., Coey J.M.D., Trinity College, IE

The use of higher uniform magnetic field intensity, such as those used in magnetic resonance imaging, is thought to exert little influence at the cellular level. There are several experimental studies that indicate that magnetic [...]

Effect of Microtopography and Cell Concentration on T Lymphoid Cell Migration during in vitro Extravasation Process

Prina-Mello A., Volkov Y., Prendergast P.J., Trinity College, IE

The locomotion of leukocyte cells has been proved to be influenced by microtopographical patterns with and without surface chemistry [Prina-Mello et al., 2003, Lo et al., 2000]. In this study, parallel grooves were microfabricated on [...]

Stochastic Analysis of Particle-Pair Transport in Brownian Ratchet Device

Retkute R., Gleeson J.P., University College Cork, IE

The motion of particle pairs in a Brownian ratchet device is studied using Langevin simulations. A Lennard-Jones interaction between the particles is added to a standard spring-bead model. The effects of such interaction upon a [...]

Taylor Dispersion in Electroosmotic Flows with Random Zeta Potentials

Gleeson J.P., Stone H.A., University College Cork, IE

Electroosmotic flows are extensively employed for fluid transport and sample separation in lab-on-a-chip technologies, capillary zone electrophoresis, and generally in channels and capillaries with length scales on the order of 100 microns or less. Experimental [...]

Modelling Annular Micromixers

Gleeson J.P., Roche O.M., West J., Gelb A., University College Cork, IE

The search for efficient mixing methods in the low Reynolds numbers flows typical of lab-on-a-chip technology has led us to propose an annular magnetohydrodynamic micromixer, currently under construction at the NMRC. In this talk we [...]
