Surface plasmon resonance sensor for food safety

Surface plasmon resonance sensors have numerous applications in the discovery of poisonous gasses, water toxins, and the biomarkers of numerous infections. Surface plasmon sensors are a great candidate for future detecting stages due to their high sensitivity and fine resolution. A surface plasmon resonance sensor is also built for food safety using a Kretschmann setup with a gold coated prism. The setup was used to detect the analyte solution with concentrations 0%-3%. The sensor showed a good response and stability.
