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.
