Seminar by Ned Seeman

On Friday the 9th of October 2009 professor Ned Seeman visited CDNA to give an iNANO lecture on "DNA: Not Merely the Secret of Life". Ned Seeman pioneered the field of structural DNA nanotechnology by suggesting and demonstrating DNA as a building block for nanoscale science. His group at NYU continues to contribute major advances to the field, recently, nanomechanical devices, DNA walkers, and DNA crystals.

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.
