摘要
Chikungunya virus has been discovered in about 60 countries of the world. It leads to joint pain, joint swelling, headache, muscle pain, and fatigue of the human body. In this work, a surface plasmon resonance (SPR)based sensor is developed to detect chikungunya virus through normal and infected platelets and plasma blood cells. The proposed SPR-based sensor uses silicon and graphene layers coated over the base of a glass prism sputtered with a silver layer. The graphene layer has the advantage of enhancing the biomolecules adsorption on the metal layer. The silicon layer between silver and graphene enhances the sensor performance. The number of graphene layers along with the thicknesses of silicon and silver layers is optimized to get the highest sensitivity of the detector. To investigate the effect of the light source wavelength, simulations are performed for four different wavelengths. The highest sensitivities exhibited by the SPR-based sensor are 393 and 160 deg/RIU for the platelets and plasma cells, respectively.
