The noble metal nanoparticles, mainly in gold related nano-
structures, have been recognized widely in various biodetections.
We briely 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.
