Introduction DNA nanoactuator Induce motion on a nanomolecuar scale By base-pairing interactions between DNA strands Have a tendency to form dimers or multimers during assembly Harmful effect on performance © 2001, SNU BioIntelligence Lab,

Operation Principle DNA nanoactuator as a thermodynamic engine Consume chemical energy, produce a waste product Monitored by FRET(Fluorescence Resonance Energy Transfer) © 2001, SNU BioIntelligence Lab,

5 Dimer Formation Not all strands properly assemble into nanoactuators
