Abstract

Developing countries have obstacles reaching quality and innovative healthcare services since there is limited access to the new technologies. Such is the case for genetic medicine, where the Deoxyribonucleic Acid (DNA) detection techniques are complex and expensive. In recent years, the development of genosensors has been of great interest, since it offers cheaper alternatives for specific DNA detection. In this work, we explored the use of multifrequency impedance measurements to detect three concentrations of DNA without labeling. The results suggest that impedance could be useful as a concentration sensitive DNA measurement parameter and then be used for the development of easy-to-use and potentially cheaper technologies.
