The results demonstrate that the monolayer MoS₃ exhibits excellent structural and thermal stability, narrow-bandgap semiconductor behavior, high carrier mobility, and pronounced mechanical anisotropy, highlighting its potential for applications in flexible electronics. Building upon this foundation, we designed a series of single-atom catalysts by anchoring transition metal atoms at distinct sulfur coordination sites (S₁, S₂, S₃) of the MoS₃ support. This work reveals that both the dopant element and its coordination site precisely regulate the catalytic activity and selectivity for the CO₂ reduction reaction (CO₂RR). Theoretical screening identified three highly promising candidates: Sc_S₂@MoS₃, Sc_S₃@MoS₃, and Ni_S₃@MoS₃. Sc_S₂@MoS₃ favors the formate pathway to HCOOH with a low limiting potential of -0.18 V. Sc_S₃@MoS₃ exclusively produces CH₃OH with a rate-determining step of *CHO → *OCHH (<i>U</i>_L = -0.58 V). Ni_S₃@MoS₃ can generate both HCOOH (<i>U</i>_L = -0.55 V) and CH₃OH (<i>U</i>_L = -0.72 V) under different potentials. Notably, Sc_S₃@MoS₃ exhibits the lowest reaction energy for methanol formation. This study provides crucial theoretical guidance for developing efficient and tunable CO₂ electrocatalysts and expands the Mo-S material family by introducing a metastable but accessible 2D MoS₃ platform with unique coordination environments for single-atom catalysis, thereby broadening the application potential of 2D materials in energy conversion and environmental remediation.</p>","PeriodicalId":93,"journal":{"name":"Nanoscale Horizons","volume":" ","pages":"2637-2653"},"PeriodicalIF":6.4,"publicationDate":"2026-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148838587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we determine for the first time that ZnO-Pd nanobolts show intrinsic oxidase-like activity. Furthermore, this attribute was used to fabricate a colorimetric immunoanalytical sensor based on nanozymes for the sensitive and specific detection of CA19-9, a biomarker for PC. In this research, immunoreagent optimization, smartphone-assisted signal analysis, and kinetic analysis of nanozyme catalytic activity were employed to enable highly sensitive detection of CA19-9. Enzyme-kinetic studies showed low Michaelis-Menten constants (<i>K</i>_M) of 0.99 mM, as well as high turnover numbers (<i>k</i>_cat) and catalytic efficiencies (<i>k</i>_cat/<i>K</i>_M) of 4.48 × 10^-4 s^-1 and 0.453 M^-1 s^-1, respectively, indicating high substrate affinity. The optimized nanozyme was functionalized with Goat anti-mouse IgG (GAM IgG), thereby facilitating antigen recognition and signal transduction. The proposed immunoassay demonstrated high analytical sensitivity (LOD of 0.000159 U mL^-1 and LOQ of 0.000482 U mL^-1) and exceptional selectivity even in complex biological matrices. Software-assisted signal processing enabled precise assessment of the limit of detection (LOD) of 0.000359 U mL^-1 and the limit of quantification (LOQ) of 0.00108 U mL^-1. The practical utility of the fabricated immunoassay was further examined using human serum, with recovery rates ranging from 100.6% to 102%, indicating high accuracy and reproducibility.

However, solute separations in this regime have stubbornly exhibited broad rejection curves where solutes with dimensions substantially smaller than the nominal pore size are rejected. The widened profile of these curves results from three distinct mechanisms. Pore-size heterogeneity convolves the single-pore response with a broad size distribution, and because Hagen-Poiseuille flow scales as the fourth power of radius, the largest pores dominate the permeate and disproportionately leak oversized solutes. Confined (hindered) transport leads to intrapore hydrodynamics, slowing a solute relative to the background solvent velocity and effectively rejecting solutes that would intuitively pass through based on size exclusion alone. Finally, the pore array presents only a limited open area to an approaching solute; under single-pass operation, a solute that does not encounter a pore mouth is recorded as rejected regardless of its size. Despite these challenges in achieving sharp separations, no fundamental phenomena preclude much narrower rejection curves in principle. Advancing toward an ideal \"step function\" rejection profile requires a systematic dissection of each broadening mechanism and a scaffolded approach where geometric, intrapore, and process architecture might collectively enable unprecedented precision in practical size-selective separations.</p>","PeriodicalId":93,"journal":{"name":"Nanoscale Horizons","volume":" ","pages":""},"PeriodicalIF":6.4,"publicationDate":"2026-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149101136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Upon dye binding and selective excitation of the MDs, efficient singlet energy transfer (ET) occurs, as evidenced by the quenching of MD photoluminescence (PL), enhanced dye emission, and the emergence of an ET-induced rise component in the dye lifetime profile. Single-particle measurements under donor-selective excitation show strong ET-induced donor-acceptor PL anticorrelation, marked by a pronounced zero-delay dip [<i>g</i>²(0)] in the antibunching cross-correlation. Additional evidence for ET comes from single-particle PL trajectory analysis showing strong temporal correlation between donor and acceptor signals, and from simultaneous donor/acceptor-channel imaging under donor-only excitation, where spatially colocalized MD images confirm ET-mediated excitation of dye molecules distributed all over the MDs. Solution-phase ensemble measurements demonstrate relatively high ET efficiency (>50%) even at low bulk dye concentrations (∼1 µM). Spatially-resolved analysis further reveals ∼55% higher ET efficiency at the MD core compared to the edges, indicating preferential dye accumulation within the cavities located mostly in the core region.
