Over the past decades, fully programmable self-assembly of colloidal nanoparticles (NPs) has long been pursued and anticipated. Toward this end, DNA, carrying information contains the strength and specificity of interaction, has been widely used in colloidal self-assembly and revolutionized a versatile route for arranging colloidal NPs in deterministic way. However, their utility for metallic colloids has been largely limited in relatively small NPs while the fully programmable assembly of larger counterparts remain elusive. Herein, we propose series of strategies covering highly uniform NP synthesis, functionalizing its surface with high density of DNA, and delicate designing of DNA nanopegboard to iron out this challenge. Benefitting from this strategy, large NPs were successfully assembled into metamolecular motifs with high structural integrity. Using these strategies as a starting point, we anticipate that even more exciting functionality could be achieved. |
