The noble metal nanoparticles, mainly in gold related nanostructures, have been recognized widely in various biodetections. We briefly review the synthesis for such nanoparticle systems and provide several model predictions for their optical properties. The surface plasmon associated spectral behaviors for several chosen elements were simulated via classical electrostatic model. The surface plasmon-related absorption and scattering spectra are well known to be strongly dependent on the size, shape, composition, and surrounding medium of nanoparticles. We focus on providing such spectral information for rod-like metal nanoparticles. In addition, absorption spectra are presented in both overall and deconvoluted forms. The later consists of spectra of both longitudinal and transverse surface plasmon modes.
