“…[9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] Recent advances in DNA-functionalization of graphene and nanotubes also suggest that this method may be expedient in onsurface synthesis of low-dimensional architectures with complex nanoscale features for flexible electronics, biosensors, and optical computing. [24][25][26][27][28][29][30][31][32][33][34][35][36] To ensure that only desired blocks interact, DNA-based structures self-assembly may use hierarchical methods: 9,10,37,38 a couple of blocks are combined at each step to form intermediates, which then act as larger building blocks for the next assembly stage. While such stage-by-stage assembly has been shown, in experiment and theory, to be successful in suppressing some spurious interactions between blocks, 9,10,37,38 the yield of the target structure is low when assembling multiple blocks.…”

Programmable self-assembly provides a promising avenue to improve upon traditional synthesis and create multi-component materials with emergent properties and arbitrary nanoscale complexity. However, its most successful realizations utilizing DNA often use complicated arduous procedures that result in low yields. Here, we employ coarse-grained molecular dynamics to uncover the ranges of temperatures and misbinding strengths needed for successful one-pot self-assembly of generic, two-dimensional (2D), and distinguishable blocks. Analysis of the energies associated with a single-stranded DNA interacting with all other sequences within a mixture revealed that the success of DNA-based assembly is primarily determined by the strongest misbinding a given sequence can encounter with a sequence highly similar to its reverse complement. This enabled us to design optimized sequence ensembles with acceptably weak and consequently rare misbinding. An estimate is provided for the maximum size of, and complexity of sequences needed to synthesize self-assembled structures with high accuracy and yield, with potential relevance for DNA-functionalized low-dimensional materials for electronics and energy storage.
