The simultaneous detection of multiple mycotoxins using a cost‐effective and point‐of‐care technology is key to ensuring food safety. In this study, a disposable biosensor with two individual sensing channels is prepared on an affordable cellulose paper substrate and used to simultaneously detect fumatoxin B1 (FB1) and aflatoxin B1 (AFB1). The biosensor pattern is outlined by polydimethylsiloxane (PDMS) and the hydrophobic interface of the sensing channels is created using octadecyltrichlorosilane (OTS). Semiconducting single‐wall carbon nanotubes (s‐SWCNTs) are deposited onto the central zones to serve as the sensing elements and SWCNTs are deposited into the bilateral areas as wire. After functionalization of the s‐SWCNTs, anti‐FB1 and anti‐AFB1 are separately immobilized on the different sensing regions to capture the targeted mycotoxins. Under the optimal conditions, this developed s‐SWCNTs‐based biosensor array achieved a limit of detection (LOD) of 8.23 pg mL<jats:sup>−1</jats:sup> for FB1 and 7.48 pg mL<jats:sup>−1</jats:sup> for AFB1. As a demonstration, spiked corn samples are measured using this biosensor and recovery rates are not inferior to commercial enzyme‐linked immune sorbent assay (ELISA) kits. Overall, the cost‐effective, highly sensitive, and multiplexed biosensor platform fabricated by this approach shows great potential for detecting multiple mycotoxins.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"1 1","pages":""},"PeriodicalIF":5.4,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142226137","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding the S–Au interaction across different scales poses major challenges. DFT provides atomic-level precision but it hardly provides insight on nanosecond scale dynamics of this interface. Alternatively, MD, although it enables modeling larger systems for longer periods, its accuracy heavily relies on the parameterization of the force fields (FF). To address this, an MD potential is fitted using DFT calculations, bridging the gap in accuracy and efficiency. At the DFT level, it is found that PBE with DFT-D3 reproduces complex approaches at a fraction of the computational cost. Separating PBE and DFT-D3 contributions reveals consistent PBE energy across molecules (chemisorption), while dispersion varies (physisorption). Thus, the interaction energy of cysteine and two short-chain alkanethiols is calculated to parameterize both Morse and Lennard–Jones (LJ) potentials. The parameterization improves the potential energy in the preferred adsorption sites: the threefold hcp and fcc with respect to the previous proposals in the literature. Furthermore, the transferability is here demonstrated. At last, these results show that LJ potentials outperform more complex Morse potentials.

This can be achieved by screening the metal with a single atomic layer of O, namely, ultra‐thin metal oxide (UTMO) layers. Cobalt tetraphenylporphyrins (CoTPP) on oxygen passivated Fe(001), with 1 ML O coverage, have revealed a molecule/substrate decoupling effect due to the formation of an ultra‐thin Fe oxide layer at the interface. However, the threshold concentration of surface O required to observe the decoupling effect has not been assessed yet. In this work, the possibility of stabilizing different ultra‐thin Pd oxide superstructures, characterized by a different number of O atoms per unit cell, is exploited to investigate the O decoupling effect on CoTPP films.

Its oxide, gallium oxide (Ga<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub>), combines a large bandgap (4.4–5.3 eV) with a high dielectric constant (≈10).
