By optimizing the sensor structure through metaheuristic optimization algorithms, sensitivity was increased. To measure blood and urine glucose concentration, these materials are used as a defect layer in one-dimensional crystal photonics, consisting of three materials: magnesium fluoride (MgF2), borosilicate glass (BK7), and orphan iodide (LiI) with refractive indices of 37/ 1, 1/5, and 1/99. By changing the concentration of glucose, the refractive index of the defect layer changes, changing the optical properties of the defect layer in the photonic crystal and the spectrum of transmitted and reflected light. According to the amount of light absorption by glucose, a wavelength range of 900-2200 nm (near infrared) was used as the input light. The transfer matrix method was used to calculate multi-layer systems. This method is based on the definition of two matrices, the boundary matrix and the diffusion matrix, which can be used to directly apply the boundary conditions. By plotting the spectrum passing through the crystal using the transfer matrix method and determining the location of the peak in the spectrum, the sensitivity of the sensor was calculated for different concentrations of glucose in blood and urine. The sensitivity obtained before optimization was 530 nm/RIU, while after optimization it reached 842 nm/RIU","PeriodicalId":504734,"journal":{"name":"ECS Journal of Solid State Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141816536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Photonic technology-based biosensors show potential for identifying malignant tissues, including brain tumors, but they are often costly, time-consuming, and computationally difficult. To address these challenges, we propose an enhanced probabilistic pyramid neural networks (EPPNN)-based hollow-core photonic crystal fiber (PCF) biosensor with terahertz refractive index (THzBio-ECPPN) for detection of cancerous brain tumors. The approach is divided into two stages: biosensor design and brain tumor detection. Initially, PCF geometry with suspended cladding and a spiral-shaped hollow-core in the terahertz (THz) band is proposed. The PCF biosensors' characteristics are then calculated using the EPPNN model. The EPPNN model's hyperparameters are modified using the circle-inspired optimization algorithm to maximize accuracy and minimize effective mode loss. The proposed biosensor is then used to identify brain tumors. Experimental evaluations utilizing MATLAB show that the suggested strategy surpasses earlier methods, with a higher sensitivity (98%). The sensor has exceptional performance characteristics, such as a high figure of merit of 1.25-1.35 RI range and sensitivity of 50000 nm/RIU, indicating its potential for precise detection of changes in refractive index. This combination of photonic crystal structures and neural networks has enormous potential for improving cancerous tumor accuracy to 99.92%, precision to 99.23%, specificity to 99.73%,and sensitivity to 99.36% of brain tumor diagnosis","PeriodicalId":504734,"journal":{"name":"ECS Journal of Solid State Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141821509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study focuses on iron oxide nanoparticles synthesized with Volvariella volvacea (GIONP) and evaluates their physical, chemical, and biological traits, including their anticancer capabilities, against traditionally made IONPs (CIONP). GIONPs, confirmed by UV-visible spectroscopy and dynamic light scattering, showed enhanced stability and consistent size distribution. They also demonstrated smaller sizes via Fe-scanning electron microscopy analysis, and X-ray diffraction and Fourier transform infrared studies verified their crystalline structure and organic functional groups. Notably, GIONPs exhibited strong antioxidant properties, low toxicity to blood cells, promising for intravenous use, and greater antimicrobial and antibiofilm activities against various bacterial strains than CIONPs. The study revealed that both GIONPs and CIONPs exhibit a similar degree of toxicity towards MDA-MB 231 cancer cells. The internalization of GIONPs within these cells was verified through a Prussian blue assay and further supported by the concentration-dependent increase in intracellular iron levels post-treatment. These findings underscore the successful formulation of GIONPs that are not only biocompatible and eco-friendly but also capped with bioactive compounds, highlighting their promising applications in the field of biomedicine.","PeriodicalId":504734,"journal":{"name":"ECS Journal of Solid State Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141822187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The zeolite materials were hydrothermally synthesized using coal fly ash and fumed silica by-products under specific environments (1.5 M NaOH, L/(Si/Al) ratio of 40, 120°C, and 24 hours), addressing environmental concerns related to wastes managment. The performance of the zeolite-graphite modified electrode (ZGME) was evaluated using voltammetric and impedance techniques at potentials between 1.2 V and -1.2 V (vs. SCE) and a frequency range of 100 kHz to 10 mHz, respectively. The results showed that the incorporation of zeolite for the first time offered notable advantages, such as affordability, simplicity, and improved oxidation-reduction current and peak resolution for arsenic. The ZGME effectively detected As(V) under neutral conditions using a phosphate buffer solution, with a concentration range of 1 x 10-3 to 1 x 10-6 mol.L-1. The sensor achieved a detection limit of 3 μmol.L-1, a quantification limit of 5 μmol.L-1, a sensitivity of 0.28 μA/μM.cm2, and exhibited good reproducibility, opening up new potential for portable zeolite-based electrochemical sensors.
