Two dimensional PNA/DNA arrays: estimating the helicity of unusual nucleic acid polymers

Chem Commun (Camb). 2004 Aug 7:(15):1694-5. doi: 10.1039/b401103a. Epub 2004 Jun 24.

Abstract

We extend the generality of nucleic acid-based structural nanotechnology by incorporating non-natural nucleic acids into a DNA double crossover (DX) molecule; visualizing two-dimensional arrays of these DX molecules by Atomic Force Microscopy (AFM) enables us to measure the helical repeat of any heteroduplex sequence capable of forming the outer arms of a DX.
