| The resulting Southern blot is considered to be the first DNA array (Southern 2000). Two studies have used whole-genome DNA arrays to explore gene expression response to environmental stimuli in E. Extended into three dimensions, these DNA arrays could act as scaffolding for building more complex materials with intricate, nanoscale structures, Seeman says. |
