The evolution of DNA nano- Received 29 December 2018 technology has brought new inspirations to this field, owing to the unprecedented programmability of Received in revised form 31 January 2019 DNA molecules. By combining with other components, DNA nanostructures can template the growth Accepted 18 March 2019 of heterogeneous materials, support delicate plasmonic devices, build smart drug delivery vehicles and Available online 28 March 2019 detect biomolecular targets. This article focuses on key strategies for DNA-based nanofabrication and highlights recent developments in chemical reactions confined on DNA nanostructures, including metal- Keywords: lization, mineralization and polymer coating. We also review applications based on DNA nanofabrication Nanofabrication and propose perspective in this field. DNA nanostructures © 2019 Elsevier Ltd. All rights reserved.
