Abstract :
We report the design, fabrication and performance of gold coated waveguide surface plasmon resonance biosensors for the detection of the pesticide simazine in aqueous solution. The operation of the sensor was verified against the biotin-avidin biochemical model. The output power of the sensor showed a decrease of 32% on binding a dual layer of biotin-avidin. Calibration of the sensor against standard simazine solutions using a competitive test format was performed and the system was determined to have a detection limit of 0.22 μg/l
