This book constitutes the thoroughly refereed post-conference proceedings of the 15th
International Meeting on DNA Computing DNA15 held in Fayetteville AR USA in June 2009. The
16 revised full papers presented were carefully selected during two rounds of reviewing and
improvement from 38 submissions. The papers feature current interdisciplinary research in
molecular-scale manipulation of matter - in particular implementation of nanoscale computation
and programmed assembly of materials are of interest thus reflecting a broader scope beyond
DNA-based nanotechnology and computation.
