Graduate Student, BBE

Nature has evolved to assemble macroscopic structures with nanoscale precision. Here, we used intelligently designed DNA strands capable of self-assembly to assemble millions of micron scaled DNA canvas capable of free nanoscale patterning. To demonstrate the drawing precision, a variation of the Mona Lisa was woven into the DNA network.
(Canvas height and width is just under a micron; Canvas thickness is 2-4 nano-meters)
