Localized surface plasmon resonance spectroscopy and sensing. (2007, background): “In particular, they studied the role of size, shape, material, and local dielectric properties—all of which determine the LSPR wavelength (20, 41, 43, 45, 58, 59).”
Localized Surface Plasmon Resonance Biosensing: Current Challenges and Approaches (2015, background): “sensitivity increases in a linear fashion as the LSPR frequency of the material shifts from blue to red wavelengths [22,23].”
Optical Biosensors Based on Plasmonic Nanostructures: A Review (2016, background): “A theoretical analysis has shown that S B depends on the optical constants of the metal and increases with the resonant wavelength, regardless of the shape of the NP [156], [157].”
Spectral optical constants of ethanol and isopropanol from ultraviolet to far infrared (2016, neutral): “However, according to the Mie theory [5] optical properties of nanoparticles are influenced by those of the dispersing medium [6], so that their dependence as a function of the surrounding refractive index is an important characteristics widely investigated in the literature [7]-[10].”
Optical properties and biomedical applications of plasmonic nanoparticles (2010, background): “Furthermore, the first theoretical studies revealed significant differences between such nanostructures as gold spheres, rods, bispheres, and nanoshells [228,229].”
