Sensing of liquid analytes via the phase shift induced by surface plasmon resonance
Original language description
A spectral interferometric technique to detect the phase shift induced by surface plasmon resonance (SPR) in the Kretschmann configuration is used in sensing small refractive index changes in a liquid analyte. The technique employs a polarimetry setup with an SPR structure comprising an SF10 glass prism, an immersion oil and a gold coated SF10 slide with a adhesion layer of chromium. In this setup two channeled spectra are recorded to detect the spectral phase shift induced by SPR. One spectrum includes reflection of p- and s- polarized waves from the SPR structure for air when the SPR phenomenon does not occur in the source spectral range, and the other one is for an analyte when the SPR phenomenon occurs. The polarimetry setup is employed to measure the spectral phase shift for aqueous solutions of ethanol. In addition, the phase shift is measured at a specific wavelength as a function of the analyte parameter, and the sensitivity is determined. The measurements are accompanied by theoretical modeling of the phase shift induced by SPR using the material dispersion characteristics, i.e., the refractive index dispersions of the SF10 glass, gold, and the analyte.
