Biosensor based on Ex-TFG coated with molybdenum disulfide

We report a Biosensor Based on Ex-TFG Coated with Molybdenum disulfide. From RI~156.342nm/RIU of bare grating to 167.739nm/RIU, then the antibody test of foot-and-mouth disease antigen detection was carried out. It was calculated that the dissociation constant K_D of the sensor was about 1.35×10^-9M, and the affinity constant KA was about 7.4×108M-1. The experimental results show that the sensor has good detection effect and good biocompatibility.
