DNA fuel for free-running nanomachines

Phys Rev Lett. 2003 Mar 21;90(11):118102. doi: 10.1103/PhysRevLett.90.118102. Epub 2003 Mar 18.

Abstract

We describe kinetic control of DNA hybridization: loop complexes are used to inhibit the hybridization of complementary oligonucleotides; rationally designed DNA catalysts are shown to be effective in promoting their hybridization. This is the basis of a strategy for using DNA as a fuel to drive free-running artificial molecular machines.
