Monitoring glucose levels in sweat is particularly significant for the diagnosis and management of diabetes, as well as for tracking the health status of diabetic patients and enabling closed-loop treatment strategies. However, challenges arise due to the presence of numerous interfering ions that complicate glucose monitoring in sweat. Additionally, the low concentration of glucose in sweat requires the use of traditional glucose sensors with immobilized enzymes to improve specificity and sensitivity, potentially leading to increased sensor costs. This study presents a novel approach of platinum-plating the surface of liquid metal to create a unique composite metal surface for a sensing electrode to solve these problems. The non-enzymatic glucose composite metal sensor, developed using in-situ platinum plating technology on liquid metal, enables specific recognition of glucose in sweat.

Subsequently, the AgNCs were stably adsorbed onto the surfaces of nano mica platelets (NMPs) via one-step synthesis to form AgNC/NMP nanohybrid surface-enhanced Raman spectroscopy (SERS) substrates with a three-dimensional (3D) lightning rod effect. The NMPs (thickness: 1–3 nm; length and width: approximately 300 nm) had a high surface-area-to-volume ratio and numerous hydroxyl groups on their surfaces, which provided the AgNCs with a good platform for stabilization and growth. When used in surface-enhanced Raman scattering for the biomolecular detection of adenine, the AgNC/NMP nanohybrids exhibited a better limit of detection (LOD) concentration of 10⁻¹⁰ M compared with AgNCs, an enhancement factor (EF) of 4.38 × 10⁹, and a relative standard deviation of 8.52 %. This may be attributed to the hot spots generated along the z-axis by the AgNC/NMP nanohybrids, which created a 3D hot spot effect. The AgNC/NMP nanohybrids also demonstrated an LOD of 10² CFU/mL in the detection of <em>Staphylococcus aureus.</em> To further improve detection sensitivity and biocompatibility, the AgNC/NMP nanohybrids were modified with zinc quantum dots (ZnO QDs) for the synthesis of AgNC/NMP/ZnO QD nanohybrids. When used for the biodetection of adenine, the ZnO-QD-modified nanohybrids exhibited a higher signal intensity compared with the AgNC/NMP nanohybrids, with an increase in the EF to 6.37 × 10⁹. The increase in intensity was attributed to the chemical enhancement effect in SERS. Excellent characteristic signals were also obtained when the AgNC/NMP/ZnO QD nanohybrids were used for the detection of the other three bases of DNA. Finally, the good biocompatibility and large specific surface area of the ZnO QDs enhanced the effects of SERS in bacterial detection, with a further decrease in the LOD to 10 CFU/mL. This also demonstrates that the prepared nanohybrid substrates were highly suitable for use in rapid and sensitive SERS biodetection.</div></div>","PeriodicalId":48517,"journal":{"name":"Materials Today Nano","volume":"29 ","pages":"Article 100601"},"PeriodicalIF":8.2,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143521079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study we report on the morphological, structural, chemical, and sensor properties of nanostructures and nanodevices subjected to hydrogen gas and other volatile compounds based on core/shell ZnO/Al₂O₃ and ZnO/ZnAl₂O₄ nanowires in dependence of annealing temperature and shell thickness.

The spinel phase provides high thermal, chemical and structural stability to the nanosensor. Core/shell ZnO/Al₂O₃ or ZnO/ZnAl₂O₄ nanowires were integrated into devices for gas sensing using a FIB/SEM system. Nanosensors based on single ZnO/ZnAl₂O₄ nanowire with a shell thickness of 5 nm showed the most promising results to the detection of hydrogen gas with an operating temperature down to room temperature, obtaining a response value of about 5 and a response value of ∼2411 at an operating temperature of 125 °C.

Achieving metal-like SERS enhancement necessitates a detailed understanding of material engineering, particularly its impact on charge transfer mechanisms and dielectric properties. In this study, we demonstrate that Ni doping in sub-stoichiometric tungsten oxide (W₁₈O₄₉) nanoflowers substantially enhances its SERS sensitivity. This improvement is attributed to increased carrier generation and alterations in the electronic band structure, which promote the photoinduced charge transfer (PICT) process. We show that Ni doping shifts the energy requirement for PICT resonance from the UV to the visible-NIR region, enabling both molecular and PICT resonance under 632.8 nm laser excitation. This “coupled resonance” effect results in an exceptionally low detection limit of 10⁻¹⁰ M and an outstanding enhancement factor of 6.85 × 10⁸ for the detection of Methylene Blue molecules, one of the highest reported for metal-free semiconductor-based SERS substrates. Additionally, the unique flower-like morphology of the material contributes significantly to electromagnetic (EM) enhancement, which is further amplified by the presence of Ni atoms. These findings are supported by finite element method (FEM) simulations and density functional theory (DFT) calculations, providing critical insights into the synergistic effects of structural and compositional tuning.
