However, fluorescence-based quantification and intracellular imaging are susceptible to interference and signal instability in thiol-rich biological environments. Herein, we report a fluorescent aptamer nanosensor based on Au-Se anchoring, which integrates a mechanistically guided anti-interference design with a calibratable, buffer-based quantitative workflow for GP73 detection. The sensing interface translates GP73 recognition into fluorescence recovery via target-induced aptamer conformational switching and increased fluorophore-gold nanoparticle distance, while the Au-Se bond mitigates thiol-driven false activation. Under optimized conditions, the assay shows a linear response in the range of 0-800 ng/mL with a detection limit of 1.51 ng/mL. Stability and tolerance studies demonstrate its robust performance across a pH range of 6.2-8.0 and in the presence of physiologically relevant concentrations of glutathione. Notably, in 5 mM glutathione, the signal increases by less than 1.5-fold compared to the untreated control, and its performance is significantly superior to that of the conventional Au-S anchored probe. Specificity experiments confirm that the probe responds significantly only to GP73, showing negligible responses to a panel of non-target proteins and a scrambled aptamer control. Preliminary serum experiments further demonstrate feasibility in a 10× diluted human serum matrix, where the probe preliminarily differentiates GP73-positive HCC patient sera from sera of other cancer patients using a ΔF strategy to reduce serum background fluorescence; however, we emphasize that the cohort size is limited and larger clinical validation is required for definitive clinical claims. Cellular experiments reveal GP73-correlated fluorescence contrast between HepG2 and normal liver (THLE-2) cells, and the thiol-depletion control (N-ethylmaleimide) supports that intracellular signal activation is thiol-independent. In summary, this work provides a robust Au-Se-stabilized nanosensor for quantitative GP73 readout in buffer and cellular imaging under thiol-rich conditions. The control experiments clearly define its specificity and anti-interference advantages, delineating key practical operating boundaries and providing a foundation for future expanded validation in complex clinical matrices.</p>","PeriodicalId":435,"journal":{"name":"Talanta","volume":"310 ","pages":"130149"},"PeriodicalIF":6.7,"publicationDate":"2026-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148300378","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, their performance is often hindered by sluggish electrode reaction kinetics and restricted cation transport channels. Herein, an organic-inorganic composite cathode, 1,4,5,8-naphthalenetetracarboxylic dianhydride (NTCDA)@VO₂, is constructed via a synergistic design strategy, in which NTCDA molecules uniformly coat and partially intercalate into the VO₂ layers, thereby optimizing electron transport and ion diffusion pathways. Compared with reported organic-inorganic composite cathodes that mainly rely on inorganic additives to improve conductivity or structural stability, NTCDA@VO₂ constructs an active organic-inorganic interface, in which VO₂ acts as an electron donor to regulate the electronic structure of NTCDA, while its layered framework enables the ordered distribution of NTCDA molecules. Benefiting from this structural synergy, the Zn//NTCDA@VO₂ battery exhibits an open-circuit voltage recovery to 1.21 V after 1 h of air exposure and delivers a high discharge capacity of 170.1 mAh g^-1 at 0.2 A g^-1. Experimental and theoretical analyses reveal that the carbonyl (C=O) groups serve as the main redox-active sites, participating in the cooperative insertion/extraction of Zn²⁺ and H⁺. Meanwhile, VO₂ acts as an electron donor when combined with NTCDA, promoting oxygen activation and reducing the oxygen reduction reaction (ORR) energy barrier from 0.91 to 0.39 eV, thereby accelerating charge transfer and ion migration.

Herein, we design a multifunctional siloxane-based electrolyte additive, 1,3,5-tris(3,3,3-trifluoropropyl)methylcyclotrisiloxane (TFSO), to regulate these coupled degradation processes. TFSO simultaneously acts as an oxygen scavenger and HF trap, suppressing lattice oxygen reactivity while converting HF into stable SiF/SiO species.

In addition, TFSO reconstructs the Li⁺ solvation structure, reducing solvent participation in interfacial side reactions.

However, its intrinsic multi-step proton-coupled electron transfer (PCET) faces a fundamental issue, which requires achieving the selective coupling of nitrogen intermediates (*NHxOy) with protons (*H) while simultaneously suppressing parasitic side reactions. To address this, density functional theory (DFT) calculations were employed to rationally screen the hybridization of Ru 4d and O 2p orbitals in oxygen-deficient RuO2, systematically evaluating it as a decisive descriptor for the adsorption characteristics of key intermediates. Building on this theoretical guidance, we synthesized monolayered RuO2 nanosheets through wet-chemical exfoliation, with oxygen-vacancy (Ovac) mediation to precisely modulate the targeted d–p hybridization. As a result, the RuO2 nanosheet with high Ovac (RuO2-HO) achieves a Faradaic efficiency of 94.3% and a production rate of 466.4 mmol h–1 g–1 at –0.4 V vs the reversible hydrogen electrode (RHE), outperforming its low-Ovac counterparts (RuO2-LO) by approximately fivefold. Complementary operando investigations and DFT calculations demonstrate that the optimized d–p hybridization in RuO2-HO balances the binding strengths toward *NHxOy and *H, thereby promoting nitrate activation and facilitating subsequent N–H coupling steps. This DFT-guided, vacancy-mediated d–p hybridization engineering establishes a versatile paradigm for the design of high-performance NRA electrocatalysts.","PeriodicalId":25,"journal":{"name":"ACS Sustainable Chemistry & Engineering","volume":"1 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2026-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149226055","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}

This work aims to report the development of a fully waste-derived carbon-sequestering binder produced by sintering at a lower temperature. A C2S-based binder was successfully produced using 55% carbide slag and 45% waste glass powder, yielding 34.3 wt % β-C2S and 24.2 wt % γ-C2S at 1100 °C. The incorporation of waste glass provided a fluxing effect due to its Na2O content, enabling C2S formation at reduced temperature. The synthesized binder achieved a compressive strength of 58.6 MPa after carbonation curing for 5 h, accompanied by a CO2 uptake of 14.6%. Mineralogical and microstructural analyses revealed calcite as the dominant carbonation product with a refined pore structure and low porosity, both of which contributed to early strength development. Moreover, it was found that an excessive raw meal Ca/Si ratio (>2.2) can significantly deteriorate the microstructure and strength of a carbonated paste. Finally, the preliminary carbon footprint assessment indicated that the synthesized binder offers a potential CO2 emissions reduction of up to 60% compared to conventional Ordinary Portland Cement production. This work establishes the feasibility of producing a 100% waste-derived, low-temperature binder that actively sequesters CO2, offering an alternative to conventional cement in the transition toward carbon-neutral construction.","PeriodicalId":25,"journal":{"name":"ACS Sustainable Chemistry & Engineering","volume":"32 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2026-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149226056","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}
