“…In our samples, the nanorod thin films are almost filled by silver, so ε rod can be roughly estimated by the dielectric function of silver ε Ag = -61.35 + 4.18 i at the working wavelength λ = 1,150 nm [29]. On the other hand, since the concentration of the glucose solution is very low, the refractive index can be expressed by a linear relation [30]…”

Sensitivity of surface plasmon resonance phase-interrogation biosensor is demonstrated to be enhanced by oblique deposited silver nanorods. Silver nanorods are thermally deposited on silver nanothin film by oblique angle deposition (OAD). The length of the nanorods can be tuned by controlling the deposition parameters of thermal deposition. By measuring the phase difference between the p and s waves of surface plasmon resonance heterodyne interferometer with different wavelength of incident light, we have demonstrated that maximum sensitivity of glucose detection down to 7.1 × 10-8 refractive index units could be achieved with optimal deposition parameters of silver nanorods.

“…This setup ensured that only resonantly reflected light of transverse electric (TE) polarization reached the spectrometer, while the transverse magnetic (TM) light component was received by a camera CCD (Thorlabs, Newton, NJ, USA) and used for navigation. The resonance wavelength relates to the fluid refractive index [ 20 ], which is proportional to concentration (in w / v % [ 25 ]).…”

Label-free, real-time detection of concentration gradients is demonstrated in a microfluidic H-filter, using an integrated photonic crystal slab sensor to monitor sample refractive index with spatial resolution. The recorded diffusion profiles reveal root-mean-square diffusion lengths for non-fluorescing and non-absorbing molecules, both small (glucose, 180 Da) and large (bovine serum albumin, 67 kDa).

“…The relationship between the solution concentration and refractive index has many applications such as measuring sea salt concentration [3] and beer quality assessment [4]. Glover et al [5] investigated the relationship between sucrose solution concentration, mass concentration, and the refractive index to establish an index characterized by the time it takes a beam of light to pass through a unit volume of a given solution. Zhang et al [6] proposed a linear correlation to a binary solution's refractive index ( An B δ = + ) based on Lorentz's electronics theory, Lambert's law, and Beer's law.…”

Variations in molar densities and solute properties, which together form a solution's basic index, can cause changes in the solution's refractive index. The linear relationship between the ternary system's refractive index solution and each solute's molar concentration can be determined through ternary system solution analysis on light passing through the solution. Experiments were conducted on a CuSO4-NaCl-H2O solution's refractive index in this study. The model utilized here can be further applied to multi-component solutions, as the solution's refractive index has a linear relationship with the properties of each solute. A new refractive index model can be derived accordingly to further enhance the results.
