Contribution à l'étude des biocapteurs à SPR

Abstract

The sensor based on "plasma surface resonance" is considered one of the most important devices used in scientific research, especially in the field of biology, in particular that biological tissues contain the refractive index that was used as the identification card and diagnosis of the mucosa and a pathological human rectum of the mucous membrane. This study necessarily involves the use of different thicknesses of gold foil to find out the sensitivity of the biological refractive index at different wavelengths. On the other hand, we proposed a structure with six layers: indicator glass, gold thin film, silicon foil, gold film and a two-dimensional layer of “PtSe2”, a sample medium through which the performance of the biosensor structure was improved in terms of sensitivity and accuracy Detection and quality factor wich is based on an algorithm that controls the parameters of the system.
