Doing research on DNA nano structures has inspired me to explore the current developments of the field in order to gain a broader understanding of the direction and capabilities of using DNA for nanotechnology. One article I came across, “A proximity-based programmable DNA nanoscaleassembly line,” published in Nature, immediately caught my interest. The paper proposes a method for using 3 different DNA-based modules in conjunction to create a working machine. Basically, what the machine does is “to put together, in a controlled fashion,a series of complex non-covalent constructs” (Gu, Chao, Xiao, Seeman 203) on a nanometer scale. This allows scientists to systematically manufacture things they would never be able to see, even under a microscope, with perfect precision. This article is just one of many examples of the amazing potential of DNA nanotechnology and the awesome things you can with physics and chemistry.
