However, the sluggish and inadequate reaction kinetics at the interface and exclusive detection of oxidizing gases restrict their sensing response and the sensing scenario. Herein, a dual-metal FeCu/NC catalyst is fabricated to facilitate the reduction reaction at the interface. The incorporation of Fe shifts the d-band center of the Cu catalyst to the Fermi level, facilitating NO2 gas adsorption and decreasing Gibbs free energy of NO2 reduction. The O atoms of NO2 will generate a covalent bond with Fe atoms, leading to an elevated charge redistribution with more electrons adsorbed by NO2 gas molecules (0.61 |e| as calculated by Bader charge analysis). As a result, the constructed sensors exhibit a remarkable NO2 sensing performance with a high response (0.16 V@10 ppm), an ultralow detection limit (10 ppb), and a fast response transience (40 s). Moreover, for H2S gas sensing, the partial Cu catalyst is oxidized to the Cu-S bond at the surface and subsequently reduced to a Cu substance at the three-phase interface, generating a lower redox potential and open-circuit voltage. As a consequence, the sensors exhibit a response of 0.1 V to 25 ppm H2S at room temperature. Finally, the sensing device is assembled into an intelligent sensing system capable of wireless information transmission for remote gas monitoring.","PeriodicalId":24,"journal":{"name":"ACS Sensors","volume":"99 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145194482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, a near-infrared (NIR)-responsive split-type SP-PEC biosensor for sensitive and specific tyrosinase (TYR) detection was constructed based on leveraging quinone-amine bioconjugation chemistry. The sensing platform consisted of a CuInS2/CuO photocathode and a MoS2/BiO2-X/Bi2S3@PDA photoanode, both designed to operate efficiently under NIR illumination. In such a sensor, dopamine (DA) played two roles, namely, as a conductive medium at the photoanode and as a substrate for TYR at the photocathode. When TYR was present, it activated DA oxidation in a 96-well microplate to generate quinones, which were then conjugated onto a chitosan-modified photocathode to behave as an electron acceptor, resulting in promoted photoelectric conversion and detection accuracy. Thus, the photocathode formed the sensing interface, and the photoanode further amplified the output signal when connected with the photocathode. Under optimum conditions, the sensor achieved an ultralow detection limit of 0.00089 U/mL with a linear detection range from 0.001 to 6.0 U/mL. Its practical applicability was confirmed through successful TYR analysis in real potato samples, validated by the high-performance liquid chromatography method. The split-type design enabled sensing without electrode-bound biorecognition elements, with the biological process separate from the photoelectrode, ensuring simplified operation, fast response, and improved accuracy.","PeriodicalId":24,"journal":{"name":"ACS Sensors","volume":"20 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145194485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Carboxylic acids, in particular, pose a significant challenge due to the strong influence of their terminal groups. In this study, we demonstrate that the chain length of aliphatic carboxylic acids can be effectively distinguished at room temperature by analyzing their adsorption-desorption behaviors on ZnO nanowire arrays. By comparing GC-MS, FT-IR, and QCM observations, we revealed that a large portion of carboxylic acids with longer alkyl chains is initially physisorbed and gradually transitions to chemisorption. To elucidate this finding, we propose an adsorption model considering a transition from physisorption to chemisorption, which slows as the alkyl chain extends due to increased van der Waals (vdW) interactions, validated by molecular dynamics simulations. Additionally, their adsorption behaviors differentiated even when exposed to mixture vapors, highlighting the potential for identifying compositions in complex mixtures. Furthermore, our investigation of other MOx surfaces reveals that Lewis acidity is crucial for carbon-number selectivity. This study underscores the previously underestimated impact of vdW interactions between alkyl chains and the ZnO surface in adsorption behavior, offering new insights for designing next-generation gas sensors.","PeriodicalId":24,"journal":{"name":"ACS Sensors","volume":" ","pages":""},"PeriodicalIF":9.1,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145190393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, C2H4 vapor is difficult to discern due to its nonpolar inertness and robust molecular structure at room temperature (RT). To this end, a new chemiresistive sensor based on bismuth selenide (Bi2Se3) decorated with zinc oxide (ZnO) nanorods was prepared in this work. Contrary to the high sensor resistance and lack of signal toward C2H4 under dark environments at RT, UV illumination endowed the composite film sensor with low resistance and a noticeable signal. Furthermore, the recovery speed was intriguingly reduced from 10 min to less than 2 min when water vapor was simultaneously introduced. In particular, the optimal 1.0-Bi2Se3/ZnO sensor delivered a response of 38.7% and a response/recovery time of 27/87 s toward 5 ppm of C2H4. Also, the long-term stability was remarkably improved with respect to the pure ZnO counterpart. In addition, excellent linearity across the concentration range from 1 to 20 ppm, good repeatability, and high selectivity over C2H4 were displayed. The effective on-site freshness detection of bananas via the as-prepared 1.0-Bi2Se3/ZnO sensor, by combining electrical signal and visual information demonstrated a huge application potential for fruit ripening monitoring under the synergistic effect of UV illumination and humidity at RT, well catering to the demanding requirements of low power consumption and high miniaturization in the field of future smart sensors.","PeriodicalId":24,"journal":{"name":"ACS Sensors","volume":"5 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145188825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Instead, we assembled all \"off-the-shelf\" parts to demonstrate the same measurement principle but with the titrant-generating electrode suspended orthogonal to the pH-sensing region of the ISFET rather than being physically deposited on the face of the chip. This offers many benefits including (1) avoiding disruption the pH functionality of the ISFET; (2) enabling the assessment of anode-gate distance sensitivity from a single ISFET; and (3) exploration of different electrode geometries and composition without complex ISFET fabrication. In this study, we analyzed the sensitivity of the AT measurement to the spacing of the titrant-generating electrode (anode) to the pH-sensing region of the ISFET (gate) as well as sensitivity to the electric current applied to the anode at three seawater AT compositions. The greatest sensor resolution in seawater was achieved when operating at a low anode current (5 μA) and greater anode-gate distance (∼150 to 200 μm) for the suspended anode configuration. The suspended anode configuration also showed an improvement in equivalence point determination with sharper inflections relative to the on-chip anode configuration.

Herein, fluorosilicone rubber (F-SiR) composites filled with vapor-grown carbon fibers (VGCFs) were fabricated, and the organic vapor sensing performance of the composites was investigated. Various F-SiR polymers with different contents (0, 50%, 100%) of trifluoropropyl groups were synthesized via ring-opening polymerization, and the addition of highly dispersed VGCF is effective in improving the electrical conductivity of F-SiR without affecting the mechanical flexibility. Consequently, the optimized VGCF/F-SiR composite film exhibits high sensitivity (>104 resistance change), relatively rapid response time (∼34 s), and good reproducibility for detecting both static-saturated and low-concentration flowing organic vapors, superior to the traditional conductive silicone rubber composites. Notably, the composites with different trifluoropropyl groups present different organic vapor-responsive behaviors. Typically, the VGCF/50%F-SiR film-based gas sensor demonstrates good sensing selectivity for both hexane and ethyl acetate and maintains a stable gas-sensing behavior after 50 cyclic blending and twisting tests or under complex environments.
