Numerical Analysis of Nanofluidic Sample Preconcentration in Hydrodynamic Flow

Wang Y., Pant K., Diffey W., Chen Z., Sundaram S., CFD Research Corporation, US

This paper presents the first, high-fidelity numerical study of nanofluidic streaming potential-based sample preconcentration. Parametric analysis is performed to capture the critical effects of pressure and background electrolyte (BGE) concentration on preconcentrator performance. Our studies [...]

Multi-physics Simulational Analysis of a Novel PCR Micro-Device

Wang Y., Pant K., Grover J., Sundaram S., CFD Research Corporation, US

While microfluidic devices for PCR amplification have critical applications in biodefense, homeland security, forensics and diagnostics, their efficient simulation and design continue to be a challenge. An experiment-only trial-and-error approach can prove to be prohibitively [...]

A Continuous Particle/Cell Sorter Using Dielectrophoresis

Wang G.R., Feng J.J., Vasantgadkar S., Pant K., Prabhakarpandian B., Krishnamoorthy S., Sundaram S., CFD Research Corporation, US

We present a novel design of a continuous microfluidic sorter for separation of cells or particles by the intelligent use of conventional negative dielectrophoresis with separation efficiency of greater than 95%. A high fidelity modeling [...]

Multi-scale, Mechano-biological Model of Nanoparticle Toxicity

Jenkins J., Pant K., Hood J., Sundaram S., CFD Research Corporation, US

Multiscale simulation of the toxic physiological effects of short and long term exposure to nanoparticles (NP) requires a unified quantitative understanding of NP deposition, partitioning of NP within the body (lung, liver, spleen, and brain), [...]

Resolved Particle Simulations of Microsphere/Cell-based Bioanalytic Systems

Pant K., Romanowicz B.F., Sundaram S., CFD Research Corporation, US

Microsphere and cell-based assays are emerging as the platform of choice for rapid quantitation of biomolecular interactions in bioagent detection, clinical diagnosis, drug therapy, etc. [1,2] Traditional assay designs have been driven by expensive trial-and-error [...]
