Manufacturing artificial nanostructures within cells

Structural DNA nanotechnology, where the nucleotides or base pairs of DNA, na01_DNA nanostructuresmely adenine (A) and thymine (T), and guanine (G) and cytosine (C) are made to self-fold into a number of different building blocks, and is a fast-growing field within nanomedicine. Up until now, the technology has been somewhat limited by the need to synthesise all of the material from scratch. Now researchers at Arizona State University’s Biodesign Institute, led by Hao Yan, have managed to harness the cell’s ability to copy DNA to make them into “factories” to replicate artificial DNA-based nanostructures.
