While analytical techniques, such as spectroscopy, spectrometry, and electrochemical sensors, are effective at detecting low concentrations, achieving attomolar sensitivity remains a significant challenge. Here, we present an electroanalytical approach that leverages partitioning kinetics to detect attomolar concentrations of redox-active analytes. Using (Cp*)2FeII as a model system, we demonstrate trace-level detection by facilitating the transfer of (Cp*)2FeII from the bulk aqueous phase into 1,2-dichloroethane (DCE) microdroplets positioned atop a gold microelectrode (radius ∼6.25 μm). This partitioning arises from the greater solubility of (Cp*)2FeII in DCE relative to its limited solubility in water, enriching the analyte concentration near the electrode as the microdroplets slowly dissolve into the aqueous phase. Additionally, we explored the role of oxygen in enhancing the electrochemical response: oxygen removal hindered detection at 1 aM, while oxygen saturation significantly amplified the redox peak signal. These findings underscore oxygen's role, which is likely a bimolecular reaction between oxygen and (Cp*)2FeII in signal amplification. An EC’ catalytic mechanism likely amplifies the electrochemical signal of (Cp*)2FeII when the droplet is sufficiently small for feedback to occur, enabling attomolar detection of (Cp*)2FeII. This study introduces a partitioning-based electroanalytical strategy taking advantage of an an EC’ catalytic mechanism for ultra-low detection limits, offering promising applications in trace chemical analysis and advanced sensor technologies.","PeriodicalId":63,"journal":{"name":"Analyst","volume":" 19","pages":" 4285-4292"},"PeriodicalIF":3.3,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12401217/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144936064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Particularly the plant toxin ricin, found in the seeds of the castor oil plant Ricinus communis, is of special forensic interest due to its worldwide availability, high toxicity, and lack of medical countermeasures. We investigated the combination of carbon and nitrogen stable isotope measurements with respective elemental composition data to provide additional forensic intelligence for sample comparison and correlation. For this, we purchased seeds from three commercially available cultivars of Ricinus communis and lipid-extracted these with three different protocols. By considering C and N stable isotope data alone, 97% of samples were correctly classified in pairwise comparison. The model was further enhanced by including total carbon and nitrogen content data, which provided information about the level of extraction and allowed the development of a normalization model based on carbon isotope ratios and carbon content. Such a model can be used not only to compare unknown samples, but also to estimate the carbon isotope ratios of original seeds and correlate potential source seeds found at a preparation site to seized extracted materials. Unlike previous approaches, this model is independent of the specific extraction method, as it reflects the systematic carbon isotope shifts across different extraction levels rather than method-specific fractionation effects. Thus, isotope ratio mass spectrometry (IRMS)-based profiling of Ricinus communis materials can help to retrospectively categorize and correlate ricin-containing materials. This information can be implemented in profiling strategies and is of high value for forensic intelligence in the context of sample comparison.","PeriodicalId":63,"journal":{"name":"Analyst","volume":" 18","pages":" 4169-4180"},"PeriodicalIF":3.3,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144870338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional tandem mass spectrometry (MS/MS) relying on collision-induced dissociation (CID) often fails to yield diagnostic fragmentation patterns for precise localization of these modifications, underscoring the need for advanced dissociation techniques. In this work, we present a novel analytical strategy combining carnitine derivatization of sphingoid amines with electron-activated dissociation (EAD) in MS2 to enable in-depth structural characterization. This technique uniquely suppresses intrachain fragmentation while generating diagnostic ions at modification sites, resulting in simplified mass spectra that facilitate unambiguous identification of subtle structural variations. This method was integrated into a reversed-phase liquid chromatography-mass spectrometry workflow and further applied for in-depth profiling of total SPHs in Astragalus and Escherichia coli (E. coli). Our analysis uncovered two pairs of regioisomeric SPHs: C<img>C positional isomers of SPH d18:1 in Astragalus and hydroxylation positional isomers of SPH t18:1 in E. coli, demonstrating the method's utility in resolving structurally complex sphingolipid bases.","PeriodicalId":63,"journal":{"name":"Analyst","volume":" 19","pages":" 4381-4388"},"PeriodicalIF":3.3,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144936030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a proprietary rapid and scalable method, hCG-selective polyacrylamide nanoMIP particles were produced within 2 h in high yields of 11 mg per 1 mL reaction batch with hCG-modified magnetic nanoparticles (MNPs@CHO@hCG). The MNPs were reusable for 5 sequential cycles of nanoMIP production. The nanoMIPs were integrated with gold screen printed electrodes by electropolymerisation within an electrochemically grown polyacrylamide layer. The ensuing hCG sensor was characterised using cyclic voltammetry and electrochemical impedance spectroscopy. Both electrochemical modes were shown to be suitable for determining the selective binding of the biomarker. The sensor was also tested using a non-target protein (SARS-CoV-2 nucleocapsid protein) and was shown to be 20× more selective for target hCG compared with the non-target. The linear range was shown to be 1.5–384 mIU with a LOD of 3 mIU and saturation occurring beyond 1000 mIU. We also electrochemically determined the equilibrium dissociation constant (KD) to be 1.4 × 10−10 M using EIS, which is on par with monoclonal antibodies produced for hCG. Sensor reusability studies demonstrated that the same sensor, once regenerated after sodium dodecyl sulphate/acetic acid treatment, could be used for 3 subsequent measurements.

The sensor design is based on a coupled configuration of a nonactin-based ammonium-selective electrode (NH4+-ISE) and a hydrogen ion-selective electrode (H+-ISE), enabling direct measurement of NH3 activity through the equilibrium: NH4+ ⇌ NH3 + H+. The resulting electrochemical cell exhibited a near-Nernstian response over a wide dynamic range, with a detection limit below 10 ppm and a response time under 6 seconds. In contrast to conventional membrane-based gas sensors, the dual-electrode system showed minimal signal drift and eliminated the need for gas-permeable membranes or internal filling solutions. Sensor performance was evaluated under various pH and ionic strength conditions, confirming matrix-independent behavior and suitability for direct application in complex environmental samples such as seawater and wastewater. The sensor also demonstrated excellent reversibility and real-time monitoring capability during dynamic NH3 fluctuation experiments in a freshwater aquaculture system, successfully tracking diurnal changes linked to photosynthetic and respiratory activity. A comparison with a commercial Severinghaus-type ammonia gas probe revealed significantly enhanced stability, faster response, and improved reproducibility for the proposed device.

In this study, a fluorescence turn-on sensor based on NU-1000 was developed for the selective detection of TCP. The fluorescence intensity of NU-1000 is significantly lower than that of the corresponding organic ligand (H4TBAPy) due to the ligand–metal charge transfer (LMCT) effect. Following the introduction of TCP, under the π–π stacking effect, the phosphate group of TCP competed with the carboxyl group of the ligand for coordination with Zr–O clusters in NU-1000, forming Zr–O–P bonds, inhibiting the LMCT effect, and triggering the metal-enhanced fluorescence (MEF) effect. This subsequently promoted the fluorescence enhancement of NU-1000. The sensor exhibited excellent linearity over the range of 0.30 to 10.0 μmol L−1, with a response time of just 2 min.
