How does particle shape influence optical properties?
Nanoparticles can exhibit unique optical properties due to their size and shape. For example, gold and silver nanoparticles display a phenomenon known as localized surface plasmon resonance (LSPR), where the shape of the particles can tune the absorption and scattering of light. Rod-shaped particles may exhibit different optical characteristics compared to spherical ones, making them useful in biosensing and photothermal therapy.
