Nanofabrication of reconfigurable metasurfaces for biosensing
Funded by the Marie Skłodowska-Curie Actions programme, the ROBOT Sensing project aims towards the reliable fabrication of bio-nano hybrid metasurfaces, using a scalable method comprising the self-assembly of DNA origami and plasmonic nanomaterials. Localised surface plasmons can be used for sensing different types of molecules, and they are very sensitive to the properties of the materials on which they propagate. DNA origami will enable the generation of the micrometre-scale plasmonic structures as templates for the arrangement of various nanoscale components. The multiple reconfigurable plasmonic switch-recognition elements coupled with lattice backbone arrays in a site-specific manner will form a metasurface for applications in nanobiosensing.
