Herein, we present a novel strategy for self-powered sensing by regulating the direct electron transfer (DET) of bilirubin oxidase (BOD) in a glucose-oxygen biofuel cell. The cathode is fabricated by immobilizing BOD on a gold nanoparticle (AuNP)-multiwalled carbon nanotube (MWCNT) nanocomposite by using an aptamer-complementary DNA (cDNA) duplex as a bridge. In the absence of aflatoxin B1 (AFB1), BOD remains distant from the AuNP-MWCNT nanocomposite, so the DET of BOD is hindered, preventing the catalytic reduction of oxygen at the cathode. In the presence of AFB1, the specific binding of the aptamer to AFB1 triggers its dissociation from the cathode, while the cDNA forms a hairpin structure due to the self-complementary sequences at both ends. The DNA structure switching brings BOD into close proximity with the AuNP-MWCNT nanocomposite, so BOD can effectively catalyze the reduction of oxygen at the cathode through DET. As a result, the biofuel cell transitions from the initial \"open-circuit\" to the \"closed-circuit\" state, enabling self-powered sensing of AFB1. The linear range for AFB1 detection is from 10-2 to 105 pg mL-1, with an ultralow detection limit of 3 × 10-3 pg mL-1. This work not only offers a novel strategy for self-powered sensing but also develops a portable device for fungal toxin detection.","PeriodicalId":50,"journal":{"name":"Langmuir","volume":"65 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145194564","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}

The classic Langmuir isotherm was integrated to capture the adsorption behavior. The model predicts the evolution of pressure, temperature, and adsorption capacity along both the axial and radial directions during the CO2 charging phase. Parametric investigations were carried out to study the effects of initial pressure, porosity, charge flow rate, and ambient temperature on system dynamics. Notably, the simulation reveals distinct thermal behavior, with the center of the tank exhibiting the highest temperature, despite having lower CO2 availability for adsorption, primarily due to the combined effects of initial temperature, heat generated from adsorption and pressure work, and thermal energy transferred from the upper regions. The total mass inside the system remained nearly constant, validating the model's accuracy through mass balance consistency.

SnS/SnSe nanostructures are considered promising candidates for sustainable energy conversion and production applications. However, their practical deployment is limited by issues such as impurity, charge carrier separation, recombination, and structural defects. Understanding their band alignment is essential to addressing these issues. This paper reports the successful synthesis of binary SnS/SnSe heterojunction nanostructures via a facile solution-based route. The study integrates experimental cyclic voltammetry (CV) and density functional theory (DFT) calculations to elucidate the electronic band structure, alignment, and offsets of binary SnS/SnSe heterojunction nanostructures. Cyclic voltammetry reveals a type-II band alignment with minimal offsets (0.07 eV CBO, 0.05 eV VBO) at the SnS/SnSe interfaces. The DFT calculations confirm these findings and elucidate the charge separation mechanism. Crucially, these small offsets enable a rapid carrier transfer. Our analysis establishes CV as a cost-effective alternative to Ultraviolet Photoelectron Spectroscopy or Scanning Tunneling Microscopy for band mapping.

These biomimetic membrane models were characterized using a combination of interface-sensitive techniques, including Langmuir monolayers, compression-expansion cycles, grazing incidence X-ray diffraction (GIXD), quartz crystal microbalance (QCM), and attenuated total reflection spectroscopy (ATR) for supported layers. These experimental methods were complemented by molecular dynamics (MD) simulations to gain molecular-level insights. The study confirms that neutral PTX interacts with all membrane components, while positively charged EPI exhibits significant interactions predominantly with the negatively charged DMPS lipid. Notably, the PTX + EPI combination demonstrated pronounced synergistic effects on both types of phospholipid monolayers, especially the ternary mixture, leading to significant membrane fluidization and the formation of irreversible aggregates. GIXD further corroborated the increased membrane fluidity and structural reorganization induced by the drug combination. QCM and ATR spectroscopy revealed substantial structural alterations and lipid rearrangement in the supported bilayers upon exposure to PTX + EPI. MD simulations suggest that these synergistic effects result from the formation of drug clusters within the lipid bilayer, influencing the physicochemical properties of the model biomembranes. These findings provide valuable insights into the interfacial interactions of anticancer drugs with lipid membrane materials, which can contribute to the development of improved combination therapies.","PeriodicalId":50,"journal":{"name":"Langmuir","volume":"33 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145188927","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}

Initially, smaller amounts of HDTMS adsorbed resulted in a disorganized film with a decomposition temperature higher than that observed for bulk HDTMS due to the molecules being directly attached to the surface. FTIR and TMDSC results confirmed that at smaller adsorbed amounts, the molecules were largely amorphous and became more crystalline at larger adsorbed amounts. At very small adsorbed amounts, it was not possible to characterize the alkylsilane at submonolayer coverage, but at larger adsorbed amounts, it was found that the enthalpies measured increased exponentially, reaching the enthalpy value for the bulk HDTMS. The exponential growth scale was found to be around 1.5 mg HDTMS/m2 of DE surface, comparable to that found on fumed silica, in spite of the much smaller specific surface area and different morphology of DE.

This study continues previous work aimed at understanding the interaction of cycline antibiotics with different HA surfaces, now incorporating the effect of hydration on adsorption energies as calculated using density functional theory. The strength of these interactions was analyzed through the quantum theory of atoms in molecules (QTAIM). The adsorption isotherm of nearly stoichiometric HA followed Langmuir-Freundlich kinetics. Minocycline exhibited higher adsorption energy than doxycycline and tetracycline. The nonhydrated adsorption behavior of minocycline is compared to earlier results for doxycycline and tetracycline, while this study also evaluates adsorption on hydrated HA surfaces for all three molecules. Minocycline displays more stable adsorption than the others, in agreement with experimental findings. Our results reveal that the influence of water cannot be neglected: although it does not prevent cycline-HA interactions, it can stabilize previously unstable configurations through hydrogen bonding between cyclines and water molecules. QTAIM analysis indicates that a combination of electrostatic interactions and medium-to-strong covalent character governs the adsorption mechanism.","PeriodicalId":50,"journal":{"name":"Langmuir","volume":"94 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145188817","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}

In this work, we present a novel approach using a CNF matrix and fungal mycelia to grow coatings directly onto a range of paper and textile substrates to enhance their liquid water resistance via a sustainable, low-energy process. We demonstrate that CNF-based mycelial coatings exhibit a water contact angle (CA) of 139.1° ± 3.5° and a water uptake of 29.6 g m-2 ± 3.5 g m-2 after 3 days of growth, compared to a CA of 27.2° ± 5.0° and a water uptake value of 80.0 g m-2 ± 12.8 g m-2 for a CNF coating alone. Furthermore, the CNF-based coating still retained excellent oil and grease barrier properties (Kit Test of 12), air permeability, and oxygen transmission rates even after at least 3 days of mycelial growth. Comparing CNFs and pulp as a matrix for the coating, we find that CNF facilitates faster growth, a higher maximum CA, and a lower water uptake than pulp. Finally, we demonstrate that both the hyphal structure and surface hydrophobicity are playing a role in water barrier functionality by comparing the grown mycelial coating to a coating of fungal hydrophobic surface proteins─hydrophobins─alone. Collectively, our work demonstrates that growing CNF-based mycelial coatings onto paper or textile substrates offers a potentially scalable solution to create water-resistant barriers on diverse substrates, creating more sustainable alternatives to single-use plastics.","PeriodicalId":50,"journal":{"name":"Langmuir","volume":"1 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145140481","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}
