Structural DNA Nanotechnology

Few weeks ago, I posted an entry on DNA origami. I thought the idea was neat and creative but little did I know there are already a lot of other stuffs going on in the world.
The field - Structural DNA Nanotechnology (SDN). The person - Paul Rathemund. He has two beautiful smiley faces on his website. Quoted from his Nature paper, "an obvious application of patterned DNA origami would be the creation of a 'nanobreadboard', to which diverse components could be added. The attachment of proteins, for example, might allow novel biological experiments.."
Just few days ago, I come across this exciting news - a group of scientists at Arizona State University's Biodesign Institute have developed the world's first gene detection platform made up entirely from self-assembled DNA nanostructures. This 'breakthrough' make possible a water soluble nanoarray which can help to build a more sensitive DNA probes.
