摘 要：These types of sensors are based on measuring responses to light emission or to illumination. Optical biosensors are based on well-founded methods including fluorescence, phosphorescence, light absorbance, photothermal techniques, chemiluminescence, surface plasmon resonance (SPR), total internal reflectance, light rotation, and polarization and could employ a number of techniques to detect the presence of a target analyte. As an example, these technical usages have been demonstrated to detect the presence of allergens, particularly peanuts, during food production.
