摘要
A method for predicting the suitability of a material to support surface plasmon resonance (SPR) at a given wavelength comprising using quantum mechanics to predict the dielectric properties of a variety of metals to thereby derive mathematical models to estimate the suitability to support surface plasmon resonance. Silver, gold and copper were found to be the three metals of choice for SPR at visible wavelengths. Both aluminium and magnesium are predicted to strongly support SPR in the UV region. A new SPR biosensor is proposed where the frequency of an illumination laser is chosen to coincide with a strong excitation peak of a surface-adsorbed fluorescent molecule, and a suitable metal is chosen to support SPR at this wavelength.
