What are the Optical Properties of These Nanoparticles?
Gold and silver nanoparticles display unique surface plasmon resonance (SPR) properties. When light interacts with these nanoparticles, it induces collective oscillations of the electrons on the nanoparticle surface, resulting in strong absorption and scattering of light at specific wavelengths. This property makes them highly beneficial for applications in biosensing and imaging.
