Paper Abstract

In this study, highly stable aqueous solutions of blends containing Deoxyribonucleic acid (DNA) and high k ceramics (BaTiO3 or TiO2) nanoparticles were processed. Dielectric and electrical properties of the as-prepared nanocomposites thin films were investigated. Dielectric Constant k values of 14 and capacitance density of 2.5 nF/cm2 were achieved for a 40 wt.% BaTiO3 loading at 1 KHz. The current-voltage (IV) measurements revealed electrical resistivity in the order of 1014 Ohm-cm with leakage current densities of the order of 10-9 A/cm2 for electric field biases up to 50V/μm.
