Simple, efficient and accurate method toward the monitoring of ethyl butanoate traces

Abstract

We introduce in this research a simple, accurate, safe, and efficient design for the detection of ethyl butanoate that be present in the dry exhaled breath. In particular, the presence of ethyl butanoate in the dry exhaled breath could be utilized as a platform for the diagnosing of COVID 19. The main idea of this theoretical investigation is based on the inclusion of a cavity layer between a thin layer of Au and the well-known one-dimension photonic crystals. Accordingly, the cavity layer is filled with dry exhaled breath. The numerical results are investigated in the vicinity of the Drude model and transfer matrix method. The investigated results show the appearance of Tamm plasmon resonance in the reflectance spectrum of our design through the IR region. Such resonant mode provides very high sensitivity with the change in the concentration of ethyl butanoate. We have examined the performance of the proposed sensor by calculating its sensitivity, detection limit, detection accuracy, quality factor and figure of merit. The designed sensor could receive sensitivity of 0.3 nm/ppm or 260,486 nm/RIU, resolution of 7 ppm and quality factor of 969.

SARS-CoV-2 detecting rapid metasurface-based sensor

“…It is proved that the higher level traces of ethyl butanoate is present in exhaled breath of COVID-19 infected patient and thus this can be employed for the rapid detection of COVID-19 [26]. Alrowaili reported a photonic crystal-based sensor to detect the ethyl butanoate with the sensitivity of 0.3 nm/ppm [27]. Patel and co-authors reviewed numerous graphene-based absorbers for several applications in solar energy harvesting, biosensing of hemoglobin, urine, glucose, etc.…”

An Efficient Photonic Crystal‐Based Chemical Sensor for the Detection of Isopropanol, Ethanol, and Acetone

“…[22][23][24][25] A simple structure of ethyl butanoate detection has been proposed. [26] The underlying principle of this sensor is the incorporation of a cavity layer in between a layer of gold and a photonic crystal in 1D. Dry exhaled breath fills the cavity layer.…”

The Transmission Properties of One-Dimensional Photonic Crystals with Gradient Materials

“…By detecting the change of defect modes caused due to the change in concentrations of the heavy metals in the contaminated water, they demonstrated their designs could be a potential way for simple and accurate detection of heavy metals in the contaminated water [16]. Also, some researchers used 1D PC of Si/SiO 2 that has a wide and high reflection PBG for the detection of ethyl butanoate, which could be promising for accurate and rapid diagnosing of COVID-19 [17].…”
