Modulating DNA adsorption on silica beads using an electrical switch

Author affiliations

Abstract

We demonstrate active tuning of DNA adsorption on silica beads using an electrical switch in a microfluidic device; we use electrolysis of water to alter pH in a packed bed of silica beads and switch the silica bead surface between being adsorptive and desorptive for DNA molecules.
