Plasmon Resonance. There is a cloud ... electromagnetic fields (like light). But when the surface of the metal is very small -- like in a nanoparticle -- the electron cloud is can begin to ...

Read more about the self-assembly of gold nanoparticles into small clusters. (Image: HU Berlin/HZB) AuNPs exhibit a strong surface plasmon resonance (SPR) effect, which is the collective oscillation ...

What is Localized Surface Plasmon Resonance? Localized surface plasmon resonance (LSPR) is a phenomenon that occurs when light interacts with conductive nanoparticles that are smaller than the ...

For instance, 100 nm spherical gold nanoparticles have a surface plasmon resonance (SPR) peak at 570 nm, while 100 nm Gold NanoUrchins display an SPR peak around 680 nm. TEM of 100 nm Gold NanoUrchins ...
