Hemoglobin, a vital protein in red blood cells responsible for oxygen transport, serves as an important biomarker for numerous health conditions. Accurate and rapid measurement of hemoglobin levels can aid in the early detection and monitoring of anemia, blood disorders, and other medical conditions. This study presents a biosensor design for hemoglobin detection, integrating a graphene-based metasurface with circular and square ring resonators constructed from silver and gold nanostructures. The proposed sensor leverages the unique plasmonic properties of plasmonic nanostructures and the remarkable optical characteristics of graphene to enhance its performance. Extensive parametric analysis and optimization are conducted to enhance detection accuracy among other performance parameters. Detection analysis demonstrated the sensor’s ability to resolve changes in hemoglobin concentration through distinct shifts in transmittance and reflectance spectra. The resulting sensor exhibits enhanced sensitivity of 3500nmRIU−1 to infrared energy, maximum FOM of 17.6, and detection limits of 0.05 among other performance parameters. Furthermore, machine learning optimization using 1D convolutional neural network regression is employed to predict the sensor’s behavior achieving high accuracy with maximum R2 scores ranging up to 1. The sensor design exhibits remarkable potential for applications requiring highly sensitive and precise hemoglobin monitoring in medical diagnostics and healthcare.","PeriodicalId":736,"journal":{"name":"Plasmonics","volume":"8 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142213400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The biosensor uses an external gold (Au) coating as the plasmonic layer to identify changes in the refractive index (RI) of various analytes. Five critical design parameters, including the diameters of the air holes and the thicknesses of both the analyte and gold layers, were optimized using the Taguchi L8(25) orthogonal array method. The optimization resulted in outstanding spectral and amplitude sensitivities, achieving 1000 nm/RIU and 98.422 RIU−1, respectively. Additionally, Multiple Linear Regression (MLR) and Multi-Layer Perceptron Artificial Neural Network (MLP-ANN) models were employed to predict the sensor’s confinement loss. The findings demonstrate the efficacy of artificial neural networks in providing quick and accurate predictions for various geometric configurations, showcasing their potential in this advanced application.

The synthesis of nickel oxide nanoparticles was achieved by employing pulsed laser ablation in water, while a PS layer was produced through light-assisted electrochemical etching. An investigation is conducted on the optical, structural, and optoelectronics characteristics of NiO-NPs/PS structures, focusing on their dependence on laser energy. The XRD analysis indicates the presence of distinct peaks corresponding to a cubic pattern, signifying the creation of nickel oxide nanoparticles on PS in the produced specimen. The field emission scanning electron microscope investigation verified that the suspension nanoparticles exhibited predominantly a sphere-like shape. The suspension of NiO nanoparticles appeared as an absorption edge at a wavelength of around 275 nm. Furthermore, it was observed that the absorption peaks became stronger with increased laser energy. The optical properties provide that the band gaps of the NiO NPs formed with laser energies between 400 and 800 mJ were identified, ranging from 4.98 to 4.85 eV, respectively. The photodetector measurements indicate that the NiO NPs/PS structures, formed at 700 mJ, exhibited maximum responsivity visible ranges of 0.065 A/W at 400 nm wavelength and 0.137 A/W at 600 nm wavelength. The results indicated that the spectral responsivity, detectivity, and quantum efficiency of the photodetectors comprised of p-NiO NPs/PS/n-Si were significantly associated with the laser energy employed to prepare the NiO NPs. The fabricated detector achieved its highest spectral response when the NiO NPs were prepared at an energy of 700 mJ. The NiO NPs/PS structures fabricated in this research, which integrate NiO NPs with Si nanostructure, suggest significant promise for deployment as highly effective photodetectors.","PeriodicalId":736,"journal":{"name":"Plasmonics","volume":"63 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142226843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, further improvements in terms of light trapping optimization and short-circuit current should be developed to overcome the efficiency limitation. In this work, a design framework based on coupling plasmon-induced charge separation gold nanoparticles (Au-NPs) and light trapping engineering using back grooves is proposed, to enhance the photovoltaic performance of the CsSnI3 solar cell. Accurate numerical models based on combined Finite Difference Time Domain (FDTD)-SCAPS calculations are performed including the influence of Au-NPs and back grooves. In addition, particle swarm optimization (PSO) technique is used to boost up the absorption capabilities of the proposed CsSnI3 solar cell, where the best distribution of Au-NPs (radius = 38 nm, period = 365 nm) and geometry of back grooves (period = 183 nm, height = 76 nm, and width = 190 nm) are successfully selected. The recorded power conversion efficiency of the proposed CsSnI3 solar cell could achieve 5.75% and a high short-circuit current of 23.3 mA/cm2 is reached by considering the optimized structure.

The propagation behavior of SPPs mode is studied by changing the constitutive parameters of chiroferrite medium and graphene features. From numerical results, it is revealed that effective mode index (EMI, phase velocity, graphene conductivity, and EM wave frequency) can be tailored by adjusting chirality, gyrotropy, and graphene features (chemical potential, number of graphene layers) in the THz frequency range.
