One-Dimensional Photonic Crystal Biosensor Based on Tamm Plasmon Resonance for Malaria Diagnosis in the Short Wavelength Infrared Band

Malaria is a terrible illness that has killed about 600,000 people annually over the past 3 years. Early diagnosis of malaria is essential to enabling treatment and lowering fatality rates. A biosensor to detect malaria in the short wavelength infrared band is created using Tamm plasmon resonance among a photonic band gap in this study. The proposed biosensor is made up of a cavity layer situated between a one-dimensional photonic crystal and a metallic layer of Ag grown on a prism. A blood sample is placed within the cavity layer. The reflection spectra of the proposed biosensor for electromagnetic waves are computed using the transfer matrix method. A healthy blood sample has a different wavelength position for the Tamm plasmon resonant dip than does a blood sample that has been infected with malaria. The proposed biosensor works through quantifying the movement in the wavelength location of the Tamm plasmon resonant dip, which can be used to identify several phases of malaria infection. Under various incident angles, the proposed biosensor's performance is optimized by modifying the Ag layer and blood sample thicknesses. The best performance is achieved at an incident angle of 42.7 degrees with a sensitivity of 26,000 nm/RIU, a figure of merit of 3.88 x 10(4) RIU-1, and a detection limit of 2.87 x 10(-6) RIU. The high performance and simple structure make the proposed biosensor a competitive device for malaria diagnosis.
