Localized Surface Plasmon Resonance Properties of Concentric Dual-Ring Nanodisk

The extinction spectral properties based on localized surface plasmon resonance (LSPR) of the concentric dual-ring nanodisk (CDRN) structure are investigated by discrete dipole approximation (DDA) and plasmon hybridization theory. The CDRN nanostructure shows flexible tunable multipole resonances in the near-infrared regime and the coupled resonance wavelengths depend on the structural parameters of the nanostructure, which has great potential in multichannel LSPR-based bio-sensing applications.

Bonding Mode

The extinction spectra and electric field distribution of an asymmetric cylindrical nanorod dimer (ACND) are calculated by discrete dipole approximation. The ACND is composed of two linear orders of cylindrical silver nanorods with different radii and lengths. The effects of the structural parameters of ACND on the localized surface plasmon resonance (LSPR) mode are also studied. Results show two resonance peaks in the extinction spectra of ACND: the higher-energy anti-bonding mode and the lower-energy bonding mode. The interaction of two hybridization plasmonic resonance modes produces an asymmetric line shape in the extinction spectra, which is considered to be a Fano resonance profile.

Receptor Layer

Metal nanoparticles have potential utilities in biochemical sensing applications owing to their localized surface plasmon resonance characteristics. To facilitate the application of localized surface plasmon resonance sensors, a simple and effective interpretation of spectra responses of metal nanoparticles to analyte was developed in this paper. Based on a bilayer structure model and a trilayer structure model, a general relationship between the peak wavelength changes of extinction spectra and the thickness of the receptor layer as well as the analyte layer was established. Both analytical analysis and chloroform vapor test experiment demonstrate that the sensing performance is greatly dependent on the receptor thickness, and a thinner receptor layer will induce a greater sensitivity. These insights can be used as guidelines in fabricating highly sensitive localized surface plasmon resonance-based biochemical sensors.
