Simulation Methodology for Dielectrophoresis in Microelectronic Lab-on-a-chip

Leonardi A., Medoro G., Manaresi N., Tartagni M., Guerrieri R., DEIS - University of Bologna, IT

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 [...]

Biochemical Binding in Microspheres-Based-Imunoassays

Prabhakarpandian B., Shah K.B., Sundaram S., Makhijani V.B., CFD Research Corporation, US

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 [...]

Separation of Long Polyelectrolytes in a Microfuluidic Channel with Constrictions: A Monte Carlo Study

Tessier F., Slater G.W., University of Ottawa, CA

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 [...]

Direct Numerical Simulation of Moving Charged, Flexible Bodies with Thermal Fluctuations

Patankar N.A., Northwestern University, US

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 [...]

Transient Analysis of Electroosmotic Flow in Nano-diameter Channels

Qiao R., Aluru N.R., University of Illinois at Urbana-Champaign, US

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 [...]

New Compact Model for Generation Drain Current Transients in Weak and Moderate Inversions of Submicron Floating-Body PD SOI MOSFETs

Ionescu A.M., Munteanu D., Swiss Federal Institute of Technology-EPFL, CH

In this paper, generation-type drain current transients, in advanced (down to 50nm gate-length) floating-body PD SOI MOSFETs are investigated by 2D numerical simulation in weak inversion operation. An original compact analytical model is derived for [...]

Physically-Based Approach to Deep-Submicron MOSFET Compact Model Parameter Extraction

Chiah S.B., Zhou X., Lim K.Y., See A., Chan L., Nanyang Technological University, SG

This paper demonstrates a physically-based approach to parameter extraction of the compact Ids model we have developed for deep-submicron technology development. A two-iteration parameter-extraction scheme is described, which improves the previous one-iteration approach. Parameter calibration [...]
