双色光纤SPR成像生物传感器

For the advantages of multi-channel, real-time detection, SPR imaging biosensor is widely used. Based on the traditional single-color SPR imaging sensor, we proposed dual-color fiber optic SPR imaging biosensor based on the inherent color selectivity of digital camera. Respectively, the red plane and the green plane gray-scale image data are extracted, and the real-time response of the sensor is analyzed from these two angles. This will result in increased sensitivity while reducing instrument costs.
