Nanoantenna Plasmonic Sensing (IMAGE) DOE/Lawrence Berkeley National Laboratory Caption Top figure shows hydrogen molecules (red) absorbed on a palladium nanoparticle, resulting in weak light scattering and barely detectable spectral changes. Bottom figure shows gold antenna enhancing light scattering and producing an easy to detect spectral shift.
