Abstract
The present study investigates the angular responses, sensitivity, detection accuracy and quality parameter of surface plasmon resonance biosensor configuration which is coated with graphene layer for the detection of Pseudomonas and Pseudomonas-like bacteria. The proposed biosensor uses attenuated total reflection method to detect the change in refractive index near the sensor surface. By comparing these results with the conventional gold layer surface plasmon resonance biosensor, it is observed that the overall performance of the proposed biosensor is improved by introducing the graphene layer. Also, the dependence of sensitivity on the number of graphene layers for the proposed sensor is plotted and analyzed.
