Numerical and Analytical Studies of AC Electric Field in Dielectrophoretic Electrode Arrays
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 [...]
Transient Analysis of Electroosmotic Flow in Nano-diameter Channels
Transient analysis of electroosmotic flow in a nano-diameter channel is presented. The time for flow to reach steady state in a nano-diameter channel for various Debye lengths is investigated by solving the Navier-Stokes equations in [...]
Direct Numerical Simulation of Moving Charged, Flexible Bodies with Thermal Fluctuations
The interaction of sub-micron scale objects with fluids is an important problem encountered in miniaturized systems. Various physical phenomena should be modeled simultaneously for a fundamental investigation of these systems. Our objective is to develop [...]
Squeezing Flow of Particles and Large Molecules Suspended in a Liquid Through Nanochannels
The presentation addresses the status of current understanding of the hydrodynamic phenomena accompanyin the motion of a nanometer-sized particle through a nanotube.
Separation of Long Polyelectrolytes in a Microfuluidic Channel with Constrictions: A Monte Carlo Study
We present Monte Carlo simulation results for the motion of long linear polyelectrolytes inside a microchannel of molecular dimensions, structured as a periodic array of wells linked by narrow constrictions. Molecules are driven in the [...]
Biochemical Binding in Microspheres-Based-Imunoassays
Microspheres (referred commonly as beads) are being extensively used in biochemical assays as supports for proteins, DNA, etc. We have successfully developed |omputational models for simulating sample detection using flowing beads. The model fully integrates [...]
Simulation Methodology for Dielectrophoresis in Microelectronic Lab-on-a-chip
Recent trends in lab-on-a-chip show a growing use of dielectrophoresis (DEP) to manipulate biological objects such as cells and organic molecules [1], [2], [3], [4]. Bringing the advances of microelectronic miniaturization into biological and clinical [...]
Macromolecules in Microdevices: Multiscale simulation of DNA dynamics in model microfluidic geometries
Simple arguments predict that the dynamics of a dissolved macromolecule confined to a channel comparable to its equilibrium coi size (~1 um for viral DNA) are quite different from those in free solution, because of [...]
