Conventional diagnostic techniques frequently face challenges related to sensitivity and specificity, which can result in delays in obtaining accurate diagnoses. To overcome these obstacles, the creation of highly sensitive and selective biosensors has emerged as a key focus of research. This paper presents the conceptualization and computational simulation of a terahertz surface plasmon resonance (SPR) sensor. The proposed sensor integrates graphene and gold metasurfaces with perovskite material, aimed at cancer detection applications. The sensor architecture is optimized to achieve optimal results. Numerical simulations are conducted to demonstrate the effects of varying graphene chemical potential and resonator dimensions on sensor performance metrics. The optimized configuration demonstrated a maximum sensitivity of 1000 GHzRIU−1 and a figure of merit of 17.241 RIU−1. Analysis of electric field distribution patterns depicts the frequency-dependent electromagnetic wave interactions within the sensor structure. The sensor design also exhibits consistent spectral characteristics, with an FWHM being 0.058 THz and quality factors ranging from 3.328 to 3.517. Furthermore, the proposed sensor demonstrates the promise for encoding applications. The proposed sensor shows considerable promise for early cancer detection applications, potentially contributing to improved diagnostic capabilities and patient outcomes in oncology.","PeriodicalId":736,"journal":{"name":"Plasmonics","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142213435","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 full vectorial finite element method is used to design and analyze the reported biosensor. The proposed sensor is based on increasing the confinement of the electric and magnetic fields at the analyte layer at the resonance frequency. Hence, any slight variation of the optical properties of the analyte sample (typically the refractive index) can be detected. We demonstrate the potential of using the reported sensor for hemoglobin (Hb) concentration and early cancer detection. The geometrical parameters are studied to maximize the sensor sensitivity of the symmetric and asymmetric designs. An absorptivity of 0.98 is achieved at 1.1 THz, which depends on the analyte sample refractive index. High sensor sensitivity of 1.08 GHz/g/dL is obtained with high Q-factor of 13.2 and FWHM (full width at half maximum) of 140 GHz through hemoglobin (Hb) concentration change from 5 g/dL to 20 g/dL. Further, an average sensitivity of 556.325 GHz/RIU is realized for cancer early detection for basal cell, breast cell, Jurkat cell and Cervical cell.

The method was based on the surface manipulation of citrate-capped silver nanoparticles by selenium in ammonia-ammonium nitrate buffer solution (pH = 9). Citric acid on the surface of nanoparticles could reduce selenium ions to Se0 atoms which can react with the silver atoms to form Ag2Se surrounding silver particles. This process resulted in the deformation and aggregation of nanoparticles which can be detected by a decrease in response intensity. The effect of important experimental parameters such as pH, buffer type and concentration, volume of silver nanoparticle solution, and incubation time on analytical response were investigated and optimized. Under the optimal conditions, the calibration graph was linear in a concentration range of 0.05 to 0.8 µmol L−1 with a detection limit of 0.024 µmol L −1.

As a popular zero-dimensional material, gold nanoparticles (AuNPs) exhibit intriguing optical properties and thus have become a promising material for many sensing detection applications. Here, we proposed a simple, efficient, and sensitive quantitative detection of creatinine by studying the relative absorbance (ΔA) of AuNPs in absence and presence of creatinine. The method relies on the aggregation of AuNPs via ligand-exchanged of citrate ions and creatinine on the surface of AuNPs to achieve colorimetric detection. With this assay, the limit of detection for creatinine was as low as 0.16 mM, and the dynamic detection range was 0.5 to 20 mM under optimized conditions. In our experiments, the specificity of the proposed method was investigated and successfully applied to detect creatinine in urine sample. It reveals that the proposed colorimetric protocol has demonstrated a high sensitivity and selectivity for creatinine, and has a potential practicability in clinical diagnostics.","PeriodicalId":736,"journal":{"name":"Plasmonics","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142213439","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}

Mie’s theory, which addresses wave scattering from spherical structures, and the point-matching method for solving field equations, are the two main mathematical tools utilized in this work. Simulations have been conducted for objects with several dual combinations of metal-dielectric materials, such as Gold metal paired with dielectrics like Alumina, PVC, Teflon, and Rexolite. This investigation also extends to objects incorporating Silver metal. The diagrams depicting the variations of the scattering cross-section versus wave frequency have been presented. It will be demonstrated that, at certain frequencies, the diagrams of the scattering cross-section exhibit peaks. These peaks indicate the state in which the densities of surface plasmon dipoles at the metal-dielectric boundary have the most significant and optimal response to the presence of an electromagnetic wave. Since the maxima in the scattering cross-section diagram occur at specific frequencies within the visible region, they can be attributed as a reason for the dominant color observed in colloidal solutions containing spherical metal-dielectric Janus nanoparticles.","PeriodicalId":736,"journal":{"name":"Plasmonics","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142213438","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}

Results show that two distinct resonant dips in the transmittance spectrum are identified in the near-infrared region, where the second dip has found to have a heightened sensitivity which is particularly advantageous for chemical and biological sensing. The study reveals that increasing the nanorod radius enhances sensor sensitivity and results in a noticeable red shift in dip positions. The sensor attains a peak sensitivity of 2105 nm/RIU at nanorod radius of 22 nm.

The structure is composed of a metal-insulator-metal (MIM) S-shaped waveguide with baffle, an analogous C-shaped resonator (ACR), and a T-shaped resonator with an annular cavity (TRAC). Employing the finite element method (FEM), the optical transmission characteristics of the structure are investigated. The results indicate that the dual Fano resonances arise from different resonators and can be independently tuned by altering the structural parameters of different resonators. Then, through adjusting the refractive index (RI) of the medium within the resonator in the range of 1.3–1.4, the RI sensing properties of the structure are also analyzed. The maximum RI sensitivity (S) and figure of merit (FOM) can be up to 2400 nm/RIU and 95.86 RIU−1. Moreover, depending on the independence of the ACR and the TRAC, the sensor has efficient biochemical sensing characteristics and is used to achieve simultaneous determination of water-soluble vitamin B1 and vitamin C. The corresponding concentration sensitivities can be up to 500 nm·ml/g and 224 nm/Cvc, respectively.
