BIOCHEMICAL SENSOR SYSTEMS ON THE BASE OF THE POROUS FILMS OF THE ALLUMINIUM OXIDE WITH GOLD NANOPARTICLES UNDER CONDITIONS OF THE TOTAL INTERNAL REFLECTANCE

Abstract

The possibility of the development of the biochemical sensor systems on the base of the films with the controlled level of the spectral selective absorption under the total internal reflection (TIR) conditions. It was demonstrated that porous Al2 O3 films with the Au nanoparticles obtained by the impulse laser deposition are characterize by the presence of the minimum at the angle dependence of the reflectance factor under TIR conditions. The optical model of the sensor system in the limits of the macroscopic Maxwell theory. The effectiveness of the use of introduced transducers was demonstrated on the case of the refractometric measurements and the monitoring of the protein-protein interactions.
