The ability to interpret information through automatic sensors is one of the most important
pillars of modern technology. In particular, the potential of biosensors has been used to …

Cancer causes one in six deaths worldwide, and 1.6 million cancer patients face annual out-
of-pocket medical expenditures. In response to these, portable, label-free, highly sensitive …

About 60 countries around the world have been found to have the chikungunya virus (ChV).
It causes the human body to become fatigued and causes joint pain, muscular soreness …

We propose a one-dimensional photonic crystal that can be used to probe pathological
tissues and identify the presence of human liver cancer cells. The identification of cancerous …

We propose an improved structure of an optical biosensor based on a photonic crystal with a
defect layer, which can detect the concentration of organic contaminants in water by defect …

This paper exhibits a detailed theoretical analysis of a photonic crystal as a gas sensor for
detecting various hazardous greenhouse gases and chemicals under the influence of an …

We introduce two novel optical biosensors based on the combination of a Weyl semimetal
and a finite one-dimensional photonic crystal to diagnose different analytes such as Jurkat …

A new approach to determining the sensitivity of refractive index sensors is proposed. It has
been shown that relative and absolute sensitivity show different results, and also, for the first …

In this paper, for the first time, analytical expressions for determination of the wavelength of
defect modes (DMs) in one-dimensional (1D) photonic crystals (PCs) with two defect layers …

The scientific community works hard on developing reliable, rapid, highly sensitive, and low‐
cost techniques to detect severe acute respiratory syndrome coronavirus‐2 (SARS‐CoV‐2) …
