Cut-and-paste single molecule nanotechnology using DNA
Regular readers of Nanodot will be aware that the nanotech uses of the exquisite molecular recognition properties of DNA include both the programmed assembly of nanoparticles (which is not atomically precise) and structural DNA nanotechnology (the atomically precise assembly of nanometer scale structures from DNA strands). A group of German scientists have developed a new slant on DNA nanotechnology by using atomic force microscopy to assemble a DNA scaffold on a surface to which molecular building blocks can then bind. (...)
