For the improvement of daily needs, the use of many chemicals is growing rapidly. Some of these compounds are harmful to human health. Moreover, due to the wide range of applications in industry, it has become necessary to develop rapid and accurate detectors for chemical compounds. Herein, a new chemical photonic structure is theoretically investigated as a detector for isopropanol, ethanol, and acetone. The proposed sensor is based on a 1D ternary photonic crystal and has the structure (Si/Si3N4/SiO2)N/cavity layer/(Si/Si3N4/SiO2)N. The organic chemical compounds are assumed to be separately infiltrated into the cavity layer. The defect layer (DLR) thickness, incident angle, number of unit cells, and the contrast between the high‐ and low‐index layers are varied and the sensitivity and quality factor are found for each case. The sensitivity can be considerably improved by increasing the DLR thickness, angle of incidence, and the contrast between the high‐ and low‐index materials. An extremely high sensitivity (2270.48, 2283.0555, and 2283.75) and quality factor (21.82 × 105, 21.48 × 105 and 21.46 × 105) are obtained for isopropanol, ethanol, and acetone. The results described earlier may pave the way for a practical and useful method of diagnosing chemical compounds.

The scientific community works hard on developing reliable, rapid, highly sensitive and low‐cost techniques to detect SARS‐CoV‐2. The current techniques can occasionally produce false positive results. The development of novel approaches for the identification of SARS‐CoV‐2 is a significant area of research because of the limitations of current methods. A biosensor based on a defective binary photonic crystal (PCL) is proposed to detect SARS‐CoV‐2 concentration in this work. The model of pathogen concentration‐dependent refractive index of the analyte is taken into consideration. The concept of operation of the PCL sensor is based on the defect mode shift when any change in the refractive index of the defect layer occurs. The transmission spectra of the PCL are plotted and studied. An optimum incident angle of 80° and a defect layer thickness of 5 μm are found. The relationship between the defect mode’s wavelength and the concentration of SARS‐CoV‐2 is investigated and a sensitivity of 2648.3 nm/RIU was attained.This article is protected by copyright.

The transmission and pathogenesis of highly contagious fatal respiratory viruses are increasing, and the need for an on‐site diagnostic platform has arisen as an issue worldwide. Furthermore, as the spread of respiratory virus continues, different variants have become the dominant circulating strains. To prevent virus transmission, the development of highly sensitive and accurate on‐site diagnostic assays is urgently needed. Herein, we present a facile diagnostic device for multi‐detection based on the results of detailed receptor‒ligand dynamics simulations for the screening of various viral strains. Our novel bioreceptor‒treated electronics (receptonics) device consists of a multichannel graphene transistor and cell‐entry receptors conjugated to N‐heterocyclic carbene (NHC). We achieved ultrasensitive multi‐detection performance without the need for sample pretreatment, which will enable rapid diagnosis and prevent the spread of pathogens. This platform can be applied for the diagnosis of variants of concern in clinical respiratory virus samples and primate models. Our multi‐screening platform can be used to enhance surveillance and discriminate emerging virus variants before they become a severe threat to public health.This article is protected by copyright.
