Surface Plasmon Resonance (SPR) is a very powerful tool for the study of biomolecular interactions, so the main objet of this internship is to use an SPR-based biosensor to detect micro-pollutants in the environment. The excitation of the surface Plasmon in this work is based on the Kretschmann configuration instead of Otto’s configuration because the distance between the metal and the prism surface reduces the SPR efficiency. The principle is to obtain the surface Plasmon resonance when a photon of incident light hits the metal surface at a certain angle of incidence, a portion of the light energy couples through the metal coating with the electrons in the metal surface layer, which then move due to excitation. The micro-pollutant will then interact with the Plasmon and will lead to the 𝜆 SPR shift due to a small change in the reflective index (permittivity) of the material near the metal surface. The detection is accomplished by measuring the changes in the reflected light obtained on a detector. By measuring the wavelength shift, we can determine the pollutant concentration in the environment.
