Schematic illustration showing the construction of C-shape wires based on DNA origami nanosheets. (a) Scheme of the DNA origami nanosheet, \({90}\hbox { nm}\times {70}\hbox { nm}\), as a template for the assembly of DNA functionalized AuNPs. (b) Three sides of the DNA nanosheet are functionalized with sequences consisting of 24 adenines (\(A_{24}\)) for binding 8 AuNPs. (c) AuNPs, \({5}\hbox { nm}\) in diameter, functionalized with thymine DNA single strands (\(T_{24}\)) and complementary to the \(A_{24}\) on the DNA origami nanosheet, are attached on specific locations by hybridization. The thymines are followed by a 5 base spacer (\(T_5\)) for increased flexibility. (d) Electroless gold deposition on the AuNPs results in formation of DNA nanosheet templated gold wires with a C-shape.
