wisebabo writes "Some researchers at Technische Universitaet Muenchen and Harvard have developed a way to make DNA 'Origami' fold up into all sorts of desired nanoscale shapes. While this has been done before, there now seems to be a much greater assortment of shapes they can create. What's particularly interesting is that they've developed some software that can be used (presumably with a DNA assembler) that will create what you want; think of CAD/CAM on a molecular scale! 'The toolbox they have developed includes a graphical software program that helps to translate specific design concepts into the DNA programming required to realize them. Three-dimensional shapes are produced by "tuning" the number, arrangement, and lengths of helices.'"
