In the present paper , we propose surface plasmon resonance biosensor in combination with a photonic crystal that works based on changing the refractive index of the biomaterial using the transfer matrix method to diagnose blood components. The proposed biosensor structure is (TiO2/ SiO2)2 / silver/ gold/ graphene , which gives a narrow angular reflectivity resonance. The performance parameters of biosensor such as sensitivity, detection accuracy reported. Our results show that the sensitivity of the proposed configuration is 150 deg /RIU, which is acceptable compared to the values reported in previous studies and shows better performance of the proposed biosensor.
