In this paper we present our current research in developing non-conductive, optically transparent electromagnetic interference (EMI) or radio frequency (RF) shielding. It uses metallic nanopowders blended with deoxyribonucleic acid (DNA) based host materials. Recent results of this DNA-based EMI shielding demonstrate 18-27dB over a frequency range of 18 - 6 GHz, respectively, with an electrical resistivity measuring > 20MΩ for a 20 μm dielectric spacing. These films were optical transparent in the visible wavelength range.
