Abstract:
Nanoparticles with different sizes, refractive indices and plasmonic profiles are synthesized, labelled with DNA and embedded in DNA-based plasmonic nanoarchitectures. The contribution of the different properties to reflectivity variation % is rationally investigated by DNA hybridization measurements using the surface plasmon resonance imaging (SPRi) technology.
