Numerical and Analytical Studies of AC Electric Field in Dielectrophoretic Electrode Arrays

Feng J.J., Krishnamoorthy S., Chen Z.J., Makhijani V.B., CFD Research Corporation, US

Manipulation of micro-sized particles and biological cells using dielectrophoresis (DEP) is an emerging technique in MEMS and nano technology[3]. This paper presents an exact solution of dielectrophoretic motion of a polarized particle in the vicinity [...]

Analysis of Sample Transport in Capillary Electrophoresis Microchip Using Full-Scale Numerical Analysis

Krishnamoorthy S., Feng J.J., Makhijani V.B., CFD Research Corporation, US

An implicit finite-volume numerical scheme has been developed to solve the three-dimensional transport equations along with fully-coupled ionization equilibria in acid/base systems. The scheme solves conservation equations for mass and momentum while satisfying the electroneutrality [...]

Computational Studies of Membrane-Based Test Formats

Krishnamoorthy S., Makhijani V.B., Lei M., Giridharan M.G., Tisone T., CFD Research Corporation, US

Membrane-based test formats provide simple, accurate and cost effective diagnoses of acute and chronic conditions in general population health. The sensitivity of the immunoassay is determined by the complex biochemical binding kinetics associated with the [...]

Analysis of Sample Injection and Band-Broadening in Capillary Electrophoresis Microchips

Krishnamoorthy S., Giridharan M.G., CFD Research Corporation, US

An implicit finite-volume numerical scheme has been developed to solve the three-dimensional transport equations that govern the electroosmotic and electrophoretic phenomena. The scheme consists of solving the ion transport equation and electro-neutrality condition coupled with [...]
