“…Electrical characteristics and electric field analysis are used to examine the differences between normal and malignant cells [5]. Furthermore, the refractive indices of various analytes emerge as a critical parameter in the development of precise biosensors [6][7][8]. Recently, a few studies have been published that are based on the tabular optical properties of a variety of tissues, but this table may not provide enough information about living cells.…”

Today, cancer disease is a significant reason for the death of many patients. In many cases, cancer is diagnosed after metastasized during the body. Thus, the earlier detection gives a better opportunity for treatment and cure. A simple 1-D binary photonic crystal with a defect layer is proposed with the structure (Si/ SiO2) N /Defect/(Si/ SiO2) N as a detector for cancerous cells. The defect layer is taken here as the patient's blood sample. Compared with the normal blood sample, the cancerous samples lead to a considerable change in the refractive index. This index variation leads to a shift in the resonant mode position which can be used to diagnose cancer cells. The transfer matrix method is employed to analyze the structure. The number of periods, defect layer thickness and incident angle are investigated to maximize the sensitivity. The sensitivity is calculated at optimized conditions and found as 2400.08 nm/RIU. This sensitivity is extremely high when compared to the most recent biosensors. All the sensor performance parameters are calculated and discussed.

This study presents an investigation on the performance of the sensitivity of a dual spidershaped surface plasmon resonance (SPR)-based photonic crystal fibre (PCF) refractive index sensor having unique design specifications. To evaluate the fibre guiding properties, Finite Element Method is used for utilising the monetarily accessible COMSOL Multiphysics version 5.3a. A gold layer has been used as the plasmonic material surrounding the fibre to ensure chemical stability, and a single fine coating of TiO 2 supported the improvement of gold attachment with the fibre. The structural air holes' design arrangement inside the PCF gives an enhanced sensitivity performance. The proposed PCF-SPR gives extremely reduced confinement losses. Numerous precise investigations on the fibre parameters show the highest amplitude sensitivity of 4233 RIU −1 in detecting the scope of the refractive index (RI) 1.32-1.41. 2.36 � 10 −6 and 1.18 � 10 −5 and are achieved as amplitude resolution and wavelength resolution, respectively. The highest confinement loss found for this sensor is recorded to be 6.22 dB/cm. The RI sensor can lead to the exact identification of organic chemicals and biological analytes for the proposed design specifications, providing good sensitivity with significantly reduced confinement loss.
