The goal of this study is to assess the influence of mass transfer phenomena on DNA hybridization kinetics in a flow-through, porous microarray for fast molecular testing. We present a scaled mathematical model of coupled convection, diffusion and reaction in porous media, which was used to simulate hybridization kinetics and to analyze the influence of convective transport on the reaction rate. In addition to computer simulations, we also present experimental data of hybridization collected on our microarray system for different flow rates.

Quantitative information about the nucleic acids hybridization reaction on microarrays is fundamental to designing optimized assays for molecular diagnostics. This study presents the kinetic, equilibrium, and thermodynamic analyses of DNA hybridization in a microarray system designed for fast molecular testing of pathogenic bacteria. Our microarray setup uses a porous, nylon membrane for probe immobilization and flowthrough incubation.
