Conception d’un biocapteur plasmonique : application pour le contrôle de l’hémoglobine dans le sang

Abstract

Surface plasmon resonance (SPR) has become an important optical biosensing technology due to its real-time, label-free, and non-invasive nature. These techniques enable rapid and ultrasensitive detection of biological analytes, with applications in medical diagnostics, environmental monitoring and agriculture. In this study, we developed an SPR biosensor for controling hemoglobin in blood. The SPR method is based on the optical measurement of refractive index changes associated with the binding of analyte molecules in a sample to biorecognize the molecules immobilized on the SPR sensor.
