Bottom-up nanotechnology has two primary approaches: assembly and synthesis. The approach of assembly exhibits smart features to collect discrete nano-objects into a defined architecture, where the small objects can be further enlarged to form an integrated structure. The smart features of synthesis, on the other hand, are as yet unexploited. Here, we show that the theme of DNA can endow the synthetic strategy with smart features. With our strategy, the branches of gold nanostars can be arranged in a predictable manner directed by single DNA helixes. The previously unknown DNA regulation effect revealed in this work is also manifested with different plasmids. The synthetic DNA nanotechnology clearly demonstrates that “synthesis-with-design” of programmable colloidal nanomaterials is possible. |
