Distance-mediated plasmonic dimers for reusable colorimetric switches : a measurable peak shift of more than 60 nm
The first reconfigurable colorimetric DNA switches based on target DNA binding are reported. This DNA binding actuates a change in the interparticle distance between gold nanoparticle dimers. A significant spectral shift of 68 nm is achievable from on-off switching. The reconfigurability is possible...
