Movement of DNA within microporous materials in an electric field — •Natascha Heinsohn, Robert Niedl, and Carsten Beta — Universität Potsdam, Potsdam Golm, Deutschland

We performed experiments with DNA fragments in different microfibre materials to investigate the molecular interaction of biopolymers under electrical force. For our experimental set up we prepared printed electrodes with conductive ink to apply a constant electric field within the fibre network. We could observe differences in mobility of DNA fragments in organic and inorganic fibre materials. Our main focus of interest is to indentify and understand these observations in dependence on DNA properties like length and structure together with fibre properties and applied electrical force. This will influence our development of low-cost and disposable devices for point-of-care diagnostics.
