Investigating nanoparticle properties in plasmonic nanoarchitectures with DNA by surface plasmon resonance imaging†
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.
