Abstract: We began exploring bio-based materials, including deoxyribonucleic acid (DNA), silk and nucleobases, for photonic and electronic applications, back in the year 2000. We uncovered that these materials have unique electromagnetic and optical properties, such as low electrical resistivity and low optical absorption loss, high optical damage threshold, high temperature and ultraviolet stability and, in the case of DNA, self-assembly properties. We have been able to cast, spin deposit, spray, print and vapor deposit these materials. Since that time we have been able to exploit these materials for use in nonlinear polymer electro-optic modulators, organic light emitting diodes, polymer capacitors and electromagnetic interference (EMI) shielding, pushing the state-of-the-art. More recently, we have seen promise for their use in frequency selective EMI shielding, two-dimensional semiconductor-based transistors and resistive memory. Will we see these promising bio materials become the materials of choice for electronic and photonic applications in the future?
