Using DNA to Power Nanostructures
DNA hybridization has been used to power a number of DNA-based nanostructures constructed out of DNA. Here some considerations that go into DNA-based motor design are briefly reviewed. The emphasis will be on the operation of toeholds, single-stranded sections of DNA that facilitate the process of strand removal during certain points in the operation of a DNA-based motor. Reaction kinetics measurements for toehold mediated strand exchange are reported. These measurements have served as a guide for choosing toehold lengths.
