“…3 The transmittance spectrum of defective 1D PCs with different values of mAbs IgG concentration in the blood Sensitivity (S) is an important parameter for a sensor. The sensitivity is defined as the change in defect state wavelength per unit refractive index [25]. We obtain the sensitivity of the proposed biosensor from the graph shown in Fig.…”

In this study, we theoretically investigate one-dimensional photonic crystal (1D PC) with a defect layer as a biosensor for the detection of COVID-19 (SARS-CoV-2) through human blood. Finite-difference time-domain method (FDTD) is used to calculate the transmission spectrum of the biosensor by using OptiFDTD software. The photonic crystal biosensor performance is measured by the transmission peak shift in resonant wavelength. The effect of the defect layer thicknesses over sensor performance is studied and optimum sensitivity of the 107,0085 nm/RIU, quality factor of 0.3702x103 and detection limit of 3.37086x10-6 RIU is achieved for designed biosensor. The simple structure, easy analysis, and available fabrication techniques make the proposed design a suitable candidate for biosensing applications.

“…The proposed model sensing mechanism is based on the coupled mode theory (Ayyanar et al, 2018) which takes place amongst the evanescent eld from the core mode that interacts with plasmonic mode at gold/Ptse 2 layer to produce robust coupling effect. Figure 2 illustrates the electric eld distribution where gure 2(a) as well as (b) displays the eld distribution for fundamental core mode and plasmonic mode.…”

Platinum Diselenide, PtSe2 is becoming highly trending owing to its fascinating optoelectronic, thermoelectric and semiconductor properties. They are non-toxic, chemically inert and allow high biomolecule absorption which makes them highly applicable in sensors to boost the sensing performance. Here, we propose Surface Plasmon Resonance (SPR) based Photonic Crystal Fiber (PCF) sensor for enhanced refractive index sensing at mid infrared wavelengths. In order to achieve this, tri-path PCF coated with hybrid layer of gold/PtSe2 which allows light to travel freely through the cladding and interact with the plasmonic material to create strong coupling effect. Finite Element Method is used for numerical examination and investigation of the sensing performance for the designed tri-path sensor.The optimized proposed sensor exhibits maximum wavelength sensitivity of 42,000 nm/RIU and maximum wavelength resolution of 2.4 x 10 -6 within the analyte range from 1.33 to 1.38, which almost covers the unknown analytes of chemical, bio and gas. Further, we achieve very low loss and unique design to accomplish high sensitivity which makes it applicable to be a future candidate in various sensing applications.
