“…It can be identified and rectified by analyzing blood components in a patient [1,2]. Blood analysis plays a keen role for the detection and prevention of hematological disorders which cause many non-communicable diseases naming cardiovasalar disease, cancer, diabete, respiratory disease, and many unnoticeable diseases which bring 50 million deaths every year worldwide [3][4][5][6][7].…”

In this paper, a photonic crystal ring resonator based bio sensor is designed to sense different blood constituents in blood in the wavelength range of 1530 nm-1615 nm for biomedical applications. The blood constituents such as hemoglobin white blood cell, red blood cell, blood sugar, blood urea, albumin, serum bilirubin direct, and ammonia are sensed for the corresponding transmission output power, Q factor, and refractive index changes. As the blood constituent has unique refractive index, the resonant wavelength and output power are varied from one to another, which are used to identify the blood constituents.

“…This section presents the estimation of the proposed THz sensor for various analytes, based on their refractive index profiles. The refractive index of the analytes that were considered varies from 1.33 to 1.8 [27][28][29]. The designed THz sensor was loaded with analytes of different refractive indices for a constant thickness of 1 µm.…”

In this paper, a graphene-based THz metamaterial has been designed and characterized for use in sensing various refractive index profiles. The proposed single-band THz sensor was constructed using a graphene-metal hybridized periodic metamaterial wherein the unit cell had a footprint of 1.395λeff × 1.395λeff and resonated at 4.4754 THz. The realized peak absorption was 98.88% at 4.4754 THz. The sensitivity of the proposed metamaterial sensor was estimated using the absorption characteristics of the unit cell. The performance of the sensor was analyzed under two different categories, viz. the random dielectric loading and chemical analytes, based on the refractive index. The proposed THz sensor offered a peak sensitivity of 22.75 GHz/Refractive Index Unit (RIU) for the various sample loadings. In addition, the effect of the sample thickness on the sensor performance was analyzed and the results were presented. From the results, it can be inferred that the proposed metamaterial THz sensor that was based on a refractive index is suitable for THz sensing applications.

“…Sensitivity and specificity of optical techniques to produce high-precision data are essential for improving the tools available in future research on blood diseases (Bendib and Bendib 2018). Photonic crystal (PhC)-based biosensor is one of these optical techniques that has been considered due to its properties such as light confinement and compression (Sharma and Sharan 2015). The sensing mechanism in photonic crystals is based on the propagating mode effective index change.…”

“…They are easy to design and can detect small changes in the refractive index with a small sample size (Zhang et al 2017). Photonic crystal ring resonator (PCRR) has the advantages of very high sensitivity, small size, high quality factor and very good light confinement (Sharma and Sharan 2015). PCRR-based sensors are used to measure temperature (Zegadi et al 2019;Rajasekar and Robinson 2018), pressure (Rajasekar and Robinson 2018;Krishnan and Robinson 2014), force and strain (Mai et al 2011), biomolecules such as DNA (Hsiao and Lee 2010).…”

In this paper, a biosensors based on a two-dimensional photonic crystal (2D PhC) waveguide including a ring resonator is designed and simulated based on refractive index changes of red blood cells. The proposed biosensor structure consists of an elliptical photonic crystal ring resonator and two linear waveguides containing silicon nitride rods in a 2D rectangular lattice with circular rods. The biosensor is utilized to detect the stages of the Plasmodium falciparum cycle in red blood cells and to diagnose malaria disease. The proposed design distinguishes with high sensitivity between normal red blood cells and cells infected with Plasmodium falciparum. This biosensor is very compact, consists of gold rods in the air background and works very well at two input central wavelengths of 0.514 μm and 1.55 μm. The finite-difference time-domain (FDTD) method is used to simulate and investigate the device. The biosensor is extremely compact which is very suitable for lab-on-chip applications and exhibits higher sensitivity at both input central wavelengths compared with that of previously reported sensors.
