These biomarkers were chosen because they are physiologically important for monitoring hydration and stress. The sensor had excellent analytical qualities that included consistent, reproducible responses against physiologically important levels. Sodium showed the greatest signal response (1.2–14.4 AU), potassium (1.0–10.0 AU), chloride (1.3–10.4 AU), and cortisol (1.1–110.0 AU). By optimizing gold nanostructures and microfluidic channels, it was possible to produce greater signal intensities and reproducibilities with the best results of gold nanorods with all the analytes. The accuracy of the data and the decrease in the error of the prediction were enhanced through the application of AI algorithms with neural networks, making an error of 0.5 mM on electrolytes and 2.1 ng/mL on cortisol. IoT transmission boasted an efficiency at 97.5% with a mean latency of 118 ms. Rapid response, high reproducibility (less than 5%), and high correlation with reference methods were all validated on human trials (R<sup>2</sup> more than 0.91). The level of cortisol was correlated significantly with the heart rate (<i>r</i> = 0.81) and the stress scores (<i>r</i> = 0.85), whereas sodium was used to evaluate hydration. Monitoring in real time during exercise provided data of 0.85–1.42 hydration index with a stress score range of 18–65%. The results confirm the possibility of the sensor to be used in personal health tracking, interface with hydration and stress management in dynamic and real-life environments.</p></div>","PeriodicalId":736,"journal":{"name":"Plasmonics","volume":"21 8","pages":"3371 - 3388"},"PeriodicalIF":5.6,"publicationDate":"2026-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149072366","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}

Periodic hollow nanocylinders are constructed on an MgF2 substrate. The metasurface achieves ultra-narrowband and high-efficiency reflection in the visible spectrum. The designed nanostructure consists of coaxially stacked MgF2, TiO2, and a-Si layers. The introduction of the high-index dielectric layer provides additional control over the multipolar interactions and modifies the radiation pathways of the resonant modes. Precise control of the nanocylinder diameter D produces narrowband reflection spectra from 450 nm to 650 nm. The FWHM remains below 9 nm. The peak reflection efficiency exceeds 98%. Blue, green, and red channels are obtained at D = 180 nm, 220 nm, and 290 nm, respectively. The spectral response originates from the dominant excitation of magnetic dipole resonances together with multipolar interference regulation. Optical impedance engineering across the multilayer configuration plays a key role. Parasitic multipolar scattering at nonresonant wavelengths is strongly suppressed. The reflection spectrum thus shows enhanced monochromaticity and purity. This strategy delivers color saturation exceeding 93%. It enables continuous and complete hue coverage. The color gamut expands to 217.2% sRGB and 140.4% Adobe RGB. This study provides a new design paradigm for ultra-high-saturation displays. It also benefits precision, narrowband optical filtering, and biomimetic intelligent optical interfaces. In addition, it offers important physical insights into nanophotonic structures governed by multipolar resonance control. </p></div>","PeriodicalId":736,"journal":{"name":"Plasmonics","volume":"21 8","pages":"3443 - 3454"},"PeriodicalIF":5.6,"publicationDate":"2026-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149072441","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}

To address this, we propose a gold nanorod dimer array where each unit cell contains two anisotropic rods. By selecting the incident polarization and designing the relative in‑plane displacements between the rods, the array allows precise manipulation of collective surface lattice resonances. It is shown that the surface lattice resonance mode can reach a Q-factor exceeding 700 with good robustness. Symmetric displacement further enables complementary switching, where the low-order and the high-order lattice resonances are selectively activated or suppressed depending on nanorod positioning at antinodes or nodes of the lattice waves.
