DNA placement of Carbon nanotubes

Thiol (sulfur *) terminated DNA wraps around Carbon nanotubes
Thiol terminated DNA wraps around Carbon nanotubes
The thiol group on the DNA prefers to bind on gold lines on a silicon surface.

AFM image of DNA-wrapped nanotubes without thiol termination
DNA-wrapped carbon nanotubes with NO thiol show no surface preferance.
AFM image of Thiol-terminated DNA-wrapped nanotubes
Thiolated-DNA-wrapped carbon nanotubes prefer Au over Si.
