The drive to improve performance and reduce cost of electronics is starting to focus on the use of materials that are exotic for the electronics industry but readily available in other fields. This category prominently includes natural biopolymers, such as silk, cellulose and DNA. DNA is famously known as the molecule that carries the genetic code of living organisms. In this presentation a review of the engineering of DNA and nucleobases into useful device constructs and structures is presented. This includes synthetic (“artificial”) DNA with custom-designed sequences and natural DNA, obtained from plants or animals, which is relatively inexpensive and widely available. Three key areas where DNA and nucleic acids have made significant contributions will be briefly reviewed: (1) the application of DNA to electronics, which has boosted the efficacy and charge control in organic optoelectronics; (2) DNA nanotechnology that has folded and twisted the molecule into specific nanostructures with impressive dexterity and hairpin accuracy; (3) DNA molecular engineering, which has used DNA as template to bond nanoparticles together, and has assembled on electrodes leading to sensitive biosensors. Selected examples of DNA-based devices will be presented.

Speaker's Biography

Andrew Steckl (Fellow, IEEE and AAAS) received his BS from Princeton and his MS and PhD from the University of Rochester. Since 1988, he has been the Ohio Eminent Scholar & Gieringer Professor of Solid State Electronics at the University of Cincinnati. Current research activities are focused on: organic and biopolymeric materials for photonic and electronic devices; electrofluidic materials and devices for nano/bio applications; chem/bio/med smart materials for diagnostics and therapy. Dr. Steckl's research has resulted in 425 publications and over 500 conference presentations. His publications have garnered ~ 9,000 citations in the technical literature, with an h-index of 52. He was awarded the Rieveschl Award for Distinguished Research and Elected Scientific Member of the Bohmische Physikalische Gesselschaft.
