Scientists in the US have developed a convenient, versatile method to organise discrete length single-walled carbon nanotubes (SWNT) into complex geometries using 2D DNA origami tiles. Constructing intricate geometric arrangements of components is one of the central challenges of nanotechnology. The origami scaffolds considered here, both rectangular and triangular, were used to organise the nanotubes: several arrangements of nanotubes were constructed, with defined tube lengths and inter-tube angles. This method allows for uniform tube lengths and positional precision, leading to the reliable assembly of SWNTs into well-structured arrays.
