Part I includes subjects underpinning the book such as a primer on DNA, the broader discipline of nanoscience, and experimental tools used by the principals in the narrative. Part II examines the field of structural DNA nanotechnology, founded by biochemist/crystallographer Nadrian Seeman, that uses DNA as a construction material for nanoscale structures and devices, rather than as a genetic material. Part III looks at the work of physicists Noel Clark and Tommaso Bellini who found that short DNA (nanoDNA) forms liquid crystals that act as a structural gatekeeper, orchestrating a series of self-assembly processes using nanoDNA. This led to an explanation of the polymeric structure of DNA and of how life may have emerged from the prebiotic clutter.
Kenneth Douglas is a member of the Research Faculty in the Department of Physics at the University of Colorado-Boulder. He received his B.A. (mathematics) and M.S. (physics) at the University of Chicago and his Ph.D. (physics) at the University of Colorado-Boulder. His area of specialization is biomimetic nanofabrication. He devised a strategy that employs the surface layers of bacterial extremophiles — e.g., Sulfolobus acidocaldarius — as masks to fabricate nanoscale periodic patterns on inorganic substrates. He is co-inventor of the first-ever U.S. patents for parallel fabrication of nanoscale multi-device structures. His work has appeared in Science, Nature, Biophysical Journal, Applied Physics Letters, Physical Review B, Surface Science, FEMS Microbiology Reviews, Journal of Applied Physics, Popular Science and elsewhere. Douglas has authored multiple book chapters and seven U.S. patents.
