Abstract:
We here show a reconfigurable DNA/plasmonic nanodevice with a precisely tunable and DNA-free interparticle gap. The nanodevice comprises two DNA boxes for the size-selective incorporation of nanoparticles in a face-to-face orientation and an underlying switchable DNA platform for the controlled and reversible adjustment of the interparticle distance.
