Hierarchical self-assembly was used to construct mesoscale DNA objects as eventual templates for molecular electronic circuitry. DNA tiles were assembled from single-stranded precursors. The tiles measure 4 nm x 12 nm x 2 nm. They can be programmed to self-assemble into larger objects, such as a 4-tile raft 37 nm long. The composition and structure of the DNA rafts were characterized in solution by biochemical assays. Rafts were imaged on mica substrates under isopropanol by non-contact modedoi:10.1109/nano.2003.1231807 fatcat:cwrx26ysofekrib3qtfjpqlxzm
