Optical waveguide sensing technology has been employed in the detection of nitroaromatics, leveraging its advantages of affordability, high sensitivity, reusability, and effective detection results. However, most current optical waveguide sensors operate on the principle of cumulative refractive index change, which necessitates extended detection times. Additionally, although many optical waveguide sensors are reusable, they often require complex and time-consuming post-processing steps for device recovery, and their detection performance significantly degrades after multiple uses, thus limiting their practical applications. In this work, we developed an evanescent field optical waveguide sensor for the detection of nitroaromatics in water, utilizing polymeric optical waveguide materials and D-π-A chromophore molecule. We integrated the sensing molecules into the hydrophobic fluorosilicone resin upper cladding material and employed the evanescent field principle to monitor changes in the optical properties of the surface sensing molecules following their interaction with nitroaromatics. This approach not only prevented contaminant penetration into the sensor, allowing for rapid device recovery, but also facilitated quick quantitative detection. Our sensor demonstrates a detection time of approximately 5 s, a recovery time of about 3 s, and achieves a detection limit of 0.11 ppm, with performance remaining largely intact after several detection cycles.</p>","PeriodicalId":462,"journal":{"name":"Analytical and Bioanalytical Chemistry","volume":" ","pages":"1885-1895"},"PeriodicalIF":3.8,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143397582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, model transferability is poor and labor-intensive (re-)calibration of models is required for related processes.

UHPLC-MS/MS is the preferred technique to separate and quantify these molecules, often optimized using a time-consuming trial-and-error approach. In this study, we applied the design of experiments (DoE) approach to systematically investigate the ionization properties of multiple oxylipin species. Fractional factorial and central composite designs were employed to detect relevant instrument parameters and optimize signal intensity in ESI-MS/MS analysis. Response surface modeling revealed distinct ionization and fragmentation behaviors between polar and apolar oxylipins, driven by their responses to interface temperature and collision-induced dissociation (CID) gas pressure. Particularly, prostaglandins and lipoxins benefit from higher CID gas pressure and lower temperatures compared to the lipophilic HODEs and HETEs to achieve optimal intensity in multiple reaction monitoring analysis. While global source parameters were optimized, analyte-specific entrance/exit potentials and collision energies required individual adjustments. The final method was applied to analyze seven oxylipin classes including leukotrienes, prostaglandins, lipoxins, resolvins, HETEs, HODE<sub>S</sub>, and HoTrEs. Although improvements in lower limits of quantification were modest (< 1 pg on-column), signal-to-noise ratios increased two-fold for lipoxins and resolvins and three- to four-fold for leukotrienes and HETEs, enhancing detection at trace levels.
