Glassy carbon electrodes are covalently functionalized with ruthenium(II) complex containing the redox active 2, 2 bipyridine, and a hydrazone ligand (BNH) via., drop casting method. This results in the electrocatalytic behavior of the modified electrode (GCE/RBNH) on the oxidation of TC. Further, the modified electrode′s sustainability was tested with various antibiotics, including different concentrations of tetracycline, and scan rates by different techniques like cyclic voltammetry (CV), linear sweep voltammetry (LSV). Then a GCE/RBNH was used to create a linear calibration curve for TC concentrations ranging from 10 to 100 μmol L−1 (R2=0.99), with a limit of detection and quantification 0.0675 μmol L−1 and 0.224 μmol L−1. The current approach, which possesses an effortless electrode modification step and offers the lowest detection limit and a comparatively wider linear dynamic range, performed better for determining TC in chicken eggs and milk samples than recently reported voltammetric methods.","PeriodicalId":72192,"journal":{"name":"Analysis & sensing","volume":"5 4","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144573469","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}

In addition to being an effective etchant, NH3 also serves as a dopant by providing N heteroatoms. However, this secondary role has not been comprehensively investigated. Moreover, the influence of N-doping on the electroanalytical performance of CNFs has not been thoroughly assessed. In this work, we have prepared CNFs of two varieties by altering the ratio of etchant and feedstock gases (NH3 and C2H2, respectively), resulting in N-doped CNFs with different doping levels. Differences were also observed in the morphology and electrochemical characteristics of the CNFs. While inner sphere redox (ISR) characteristics were not significantly affected, a significant shift between the peak potentials of ascorbic acid (AA) and dopamine (DA) was detected in the higher doped CNFs, resulting in enhanced selectivity towards DA. Our results demonstrate a simple yet effective method for enhancing the electroanalytical properties of CNFs.","PeriodicalId":72192,"journal":{"name":"Analysis & sensing","volume":"5 4","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/anse.202400097","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144574239","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analyte displayed excellent electrochemical activity on the surface of nAg/Cu2O modified paper electrode and showed a concentration-dependent response between 0.05 to 500 μM with a detection limit (S/N=3), 0.04 μM. Furthermore, the anti-interference studies revealed that the nAg/Cu2O nanocomposites have high selectivity towards ascorbic acid. Notably, the sensor based on nAg/Cu2O showed exceptional stability and reproducibility, with a relative standard deviation for peak currents measuring approximately 7 % or less while testing for a week of time.

Metal oxide nanostructures (MONs) have emerged as key materials in this research because of their large surface area, adjustable electrical characteristics, and sensitivity to gaseous biomarkers at trace quantities. This paper examines current advances in chemiresistive MON-based sensors, focusing on the importance of structural optimization, hybrid material systems, and functionalization strategies in improving performance. Exploring the study of complicated datasets, the prediction of biomarker signatures, and dynamic aims in tuning the quality of the sensors. Functionalization strategies also play a vital role in enhancing the performance of MON-based sensors. By modifying the surface chemistry of chemiresistive metal oxides, researchers can tailor the sensors to preferentially adsorb certain gaseous biomarkers while minimizing interference from other compounds present in breath. Future opportunities include the development of multimodal sensors, simplified and portable devices, and durable, reusable platforms capable of long-term operation in real-world environments. With the confluence of nanotechnology and data-driven analytics, MON-based breath sensors have the potential to transform customized healthcare by providing worldwide early detection, illness monitoring, and preventative medication.","PeriodicalId":72192,"journal":{"name":"Analysis & sensing","volume":"5 4","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144573691","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}

In this work, a novel coated microneedle colorimetric sensing platform is designed to rapidly and sensitively detect total phenolic compounds (TPC) in fruits and vegetables, which is the key indicator of their nutritional and antioxidant properties. The platform utilizes a swollen microneedle structure to efficiently collect juice samples, enhancing detection efficiency through colorimetric analysis and eliminating the complexity of traditional methods. The microneedles are fabricated from a composite material consisting of 10,12-pentacosadiynoic acid (PCDA) and methacrylated gelatin (GelMA), with a secondary layer containing α-cyclodextrin to selectively bind polyphenols, thereby inducing a visible color change for the specific detection of TPC. The colorimetric response is directly correlated with the concentration of TPC, facilitating on-site analysis. Using phenol as a model molecule, the detection range of the system for phenol is 10–60 mM, with an LOD of 0.5 mM. Furthermore, a mobile application enables portable detection and analysis, reducing detection time from several hours to just 30 min. This technology offers a promising approach for the rapid, reliable monitoring of phenolic content in fresh produce, with potential applications in food quality control, nutritional analysis, and agricultural monitoring.","PeriodicalId":72192,"journal":{"name":"Analysis & sensing","volume":"5 4","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144574197","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}
