Plasmonic properties of the spherical coral-shaped gold nanoparticles induced by Pep-1. a Hyperspectral UV-Vis extinction of six individual particles revealing well-defined plasmon resonances centered at ~528 nm. b Three-photon photoemission electron micrograph of a sparse distribution of particles showing the photoemission enhancement map (scale bar, 50 nm), in which a single-coral-shaped particle (the insert) exhibited a plasmonic enhancement as high as 105 (scale bar, 20 nm)
