Unveiling Stability Criteria of DNA-Carbon Nanotubes Constructs by Scanning Tunneling Microscopy and Computational Modeling
Figure 2
STM data and theoretical interpretation: (a) nm STM topographic image of CNT-DNA hybrids on Si(110) substrate acquired at pA and V at 50 K; (b) height profile along Section A; (c) statistical distribution of characteristic lengths of periodic modulations extracted from height profiles along the Section A. (d) Optimized structures of (6,5) tube wrapped in GAGAAGAGAGCAGAAGGAGA-oligomer. For the simulated geometry, the average period of DNA helices along the tube is nm and the wrapping angle is °, which are in good agreement with an STM experiment.
