Abstract

DNA origami have the potential to serve as self-assembling circuit boards for nanoelectronic devices. This paper focuses on understanding just one aspect of the hierarchical self-assembly of DNA origami--the oligomerization of individual origami to form chains of aligned and oriented origami. The eventual goal is to place small numbers of nanomagnets in specific locations on the DNA origami in such a way that the self-assembly of the origami causes a magnetic cellular automaton device, such as a wire, to be formed. Four strategies for forming well ordered chains of DNA origami were compared by examination of AFM images of DNA origami chains deposited on mica. Preliminary results of patterned deposition of DNA origami on lithographic patterns are also reported.
