The nonlinear electromigration of analytes into confined spaces
Zhen Chen, Sandip Ghosal
We consider the problem of electromigration of a sample ion (analyte) within a uniform background electrolyte when the confining channel undergoes a sudden contraction. One example…
Strongly nonlinear waves in capillary electrophoresis
Zhen Chen, Sandip Ghosal
In capillary electrophoresis, sample ions migrate along a micro-capillary filled with a background electrolyte under the influence of an applied electric field. If the sample conce…
A nonlinear equation for ionic diffusion in a strong binary electrolyte
Sandip Ghosal, Zhen Chen
The problem of the one dimensional electro-diffusion of ions in a strong binary electrolyte is considered. In such a system the solute dissociates completely into two species of io…
Does buckling instability of the pseudopodium limit how well an amoeba can climb?
Sandip Ghosal, Yoshio Fukui
The maximum force that a crawling cell can exert on a substrate is a quantity of interest in cell biomechanics. One way of quantifying this force is to allow the cell to crawl agai…
Electrokinetic-flow-induced viscous drag on a tethered DNA inside a nanopore
Sandip Ghosal
Recent work has shown that the resistive force arising from viscous effects within the pore region could explain [Ghosal, S. Phys. Rev. E. vol. 71, 051904 (2006) and Phys. Rev. Let…
Nonlinear waves in capillary electrophoresis
Sandip Ghosal, Zhen Chen
Electrophoretic separation of a mixture of chemical species is a fundamental technique of great usefulness in biology, health care and forensics. In capillary electrophoresis the s…
