Abstract
Significance The traditional, Edisonian method of research involves taking a system and examining its properties. A preferred alternative is to target a suite of properties and then design the most appropriate system in this context. Here we illustrate such a design approach for the self-assembly of colloids grafted with single-stranded DNA. When two types of colloids grafted with complementary ssDNA sequences are mixed, DNA hybridization can lead to the formation of ordered colloidal crystals. We use the genetic algorithm to design ssDNA-grafted particles that will assemble into a desired structure. Our methodology is easily generalizable, fast and highly selective, and not only accurately reproduces the parameters relevant to four currently realized crystals but also elucidates four currently unobserved structures.
