In this paper, a graphene-coated surface plasmon resonance sensor is designed for the examination of Rodent urine which is responsible for Leptospirosis bacteria. Rodent urine is considered as sensing medium. Graphene surface is activated by phosphate-buffered saline solution for better attachment of Leptospirosis bacteria on its surface. Oliguria and Polyuria are the Rodent urine with high and low concentrations of Leptospirosis bacteria, respectively. The transfer matrix method is used for the formulation of reflection intensity of p-polarized light. The reflectance curves for angular interrogation are plotted and the results are obtained in terms of sensitivity, detection accuracy, and quality factor. The significantly high sensitivity and detection accuracy for Oliguria distinguishes it from Polyuria having lower sensitivity.

在本文中，设计了一种石墨烯涂层的表面等离子体共振传感器，用于检查负责钩端螺旋体细菌的啮齿动物尿液。啮齿类动物的尿液被认为是感应介质。石墨烯表面被磷酸盐缓冲盐溶液活化，以使钩端螺旋体细菌更好地附着在其表面上。少尿和多尿分别是具有高和低浓度钩端螺旋体细菌的啮齿动物尿液。传递矩阵法用于制定p偏振光的反射强度。绘制了用于角度询问的反射率曲线，并获得了灵敏度，检测精度和品质因数方面的结果。寡尿症的极高灵敏度和检测精度使其与灵敏度较低的多尿症区分开来。
