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 ...

Plasmon-mediated chemical reactions have revolutionized the way we manipulate and control chemical transformations with light, leveraging the unique properties of surface plasmons in noble metal ...

But please don't drink this The color of gold nanoparticles depends on their physical size, ranging from light red to a dark bluish/purple. This phenomenon is caused by Plasmon Resonance.
