Využití povrchové plazmonové rezonance pro senzoriku kapalných analytů

Abstract

The bachelor thesis is focused on problematics of the surface plasmon resonance phenomenon in the visible part of the spectrum of light. The theoretical analysis and measurement of spectral dependence of reflectance and spectral phase shift between s and p polarizations in structure of four layers in Kretschmann configuration for aqeous analytes consisting of a mixture of distilled water and ethanol in various weight ratios are performed. In addition, an experiment demonstrating the sensorics of liquid analytes using the SPR phenomenon for this four-layer system is designed to measure changes of reflectance at one wavelength.
