Signals generated from Surface-Enhanced Raman Spectroscopy (SERS) show large enhancements when a molecule is in the gap between two metal nanoparticles in close proximity. We demonstrate here a DNA-based conformationally switchable nanodumbell structure that modulates the interparticle distance between two gold-silver core-shell nanoparticles to induce significant changes in SERS signal.
