Selective formation of a latticed nanostructure with the precise alignment of DNA-templated gold nanowires.
A very efficient method is introduced to selectively align and uniformly separate λ-DNA molecules and thus DNA-templated gold nanowires (AuNW's) using a combination of molecular combing and surface-patterning techniques. By the method presented in this work, it is possible to obtain parallel and latticed nanostructures consisting of DNA molecules and thus DNA-templated AuNW's aligned at 400 nm intervals. DNA-templated AuNW's are uniformly formed with an average height of 2.5 nm. This method is expected to hold potential for the integration of nanosized building blocks applicable to nanodevice construction.
