CDNA highlights

Single-molecule chemical reactions on DNA origami

Researchers at the Danish National Research Foundation’s Centre for DNA Nanotechnology (CDNA) at iNANO demonstrate that it is possible to control chemical reactions on DNA nanostructures and generate images of reactions of individual molecules. The results were published on 28 February in Nature Nanotechnology. The article is available here

CDNA news

May 2010: DNA nano-spider published in Nature

CDNA collaborator Hao Yan publishes the paper "Molecular robots guided by prescriptive landscapes". A molecular nanorobot dubbed a "spider" and labeled with green dyes traverses a substrate track built upon a DNA origami scaffold. It journeys towards its red-labeled goal by cleaving the visited substrates, thus exhibiting the characteristics of an autonomously moving, behavior-based robot at the molecular scale.

In the same issue of Nature DNA origami was used to create an assembly line for synthesizing gold nanoparticles.
