Plasmonic nano-aperture label-free imaging (PANORAMA)

Plasmonic nano-aperture label-free imaging (PANORAMA)

Here, the authors report on an imaging method based on localized surface plasmon resonance excitation, employing gold nanodisk arrays as substrates that enable imaging of transparent dielectric particles of several sizes. They demonstrate the ability to detect and image particles smaller than the di...
