Here, a fully Cd-free, lead-free heterojunction PSC with the architecture Al/FTO/In2Se3/RbSn0.5Ge0.5I3/CuI/Ni is systematically designed and optimized using SCAPS-1D. Seven electron transport layers (In3Se4, CdS, WS2, IGZO, SnS2, ZnSe, In2Se3) and five hole transport layers (GO, GQD, PEDOT:PSS, CuSCN, CuI) are screened, identifying In2Se3 and CuI as the optimal pair owing to their favorable spike-type conduction-band offset (+0.20 eV) and zero-eV valence-band offset, which suppress non-radiative interfacial recombination as confirmed by Nyquist impedance analysis. Comprehensive optimization of absorber thickness, carrier concentration, bulk and interface defect densities, operating temperature, back-contact work function, parasitic resistances, capacitance–voltage and capacitance–frequency response, carrier generation/recombination dynamics, and electric-field distribution is performed. Under optimized conditions, the device delivers a power conversion efficiency of 26.01%, with Voc = 0.85 V, Jsc = 38.43 mA cm−2, and FF = 79.70%, surpassing previously reported RbSn0.5Ge0.5I3-based architectures.

While the effects of thermal annealing on platinum (Pt) thin films are well established, the influence of fabrication-related thermal budgets associated with OoC manufacturing has not been systematically correlated with device performance. Here, we establish a direct processing–microstructure–device performance relationship for Pt-based resistance temperature detectors (RTD). Using Si/Pt and Si/SiO2/Pt architectures, we investigate the impact of thermal annealing (up to 900°C) on film morphology and electrical properties and correlate them with device-level sensing performance. Moderate annealing temperatures (≈300°C), representative of oxide passivation processes, significantly improve electrical performance, reducing resistivity by up to 40% and increasing the temperature coefficient of resistance (TCR) through stress relaxation and grain coarsening. Higher annealing temperatures induce surface roughening and morphological instability, compromising sensor reliability. A SiO2 interlayer delays degradation and reduces resistivity drift, preserving film integrity under harsh thermal conditions. These results demonstrate that the thermal budget associated with dielectric passivation can be exploited to optimize RTD performance while defining practical processing windows for reliable integration into OoC and other biointegrated microsystems.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"13 18","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.70642","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149029120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conducting polymers have attracted considerable interest for biomedical applications owing to their reversible redox behavior and ability to accommodate therapeutic agents. In this work, we report a redox-active antibacterial coating based on poly(3,4-ethylenedioxythiophene) (PEDOT) loaded with ceftazidime (CAZ), designed to link antibiotic release to bacterial electroactivity. A high charge storage capacity (14.6 ± 3.4 mC cm−2) together with an increased charge transfer resistance (10.7 ± 0.5 kΩ) indicated successful incorporation of CAZ within PEDOT matrix. Negligible passive release of CAZ (1.2 ± 0.1 µg cm−2) was noted when compared with bacteria-induced release in the presence of Shewanella oneidensis (44.4 ± 9.0 µg cm−2) and Pseudomonas aeruginosa (62.2 ± 2.8 µg cm−2), as well as electrically-induced release (49.5 ± 5.9 µg cm−2). Spectroelectrochemical and impedance data revealed that the redox state of PEDOT was modulated in a species-dependent manner. The presence of PEDOT@CAZ limited the viability of S. oneidensis and P. aeruginosa to 13% and 20%, respectively. These findings indicate that PEDOT@CAZ acts as an intelligent antibacterial surface, releasing antibiotics in response to bacterial activity.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"13 18","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.70647","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149029144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we investigate the impact of imide substitution with bulky 2,6-isopropylphenyl (iPr) on the structural and electronic properties of perylene diimide (PDI) monolayers on Ag(111). By combining scanning tunneling microscopy, X-ray absorption and photoemission spectroscopies, we identify two distinct molecular configurations coexisting within an ordered herringbone arrangement. Core level photoemission spectra of monolayer iPr-PDI reveal two chemically inequivalent oxygen species, which originate from the sterically driven differences in adsorption height. This structural inequivalence translates into markedly different electronic coupling: molecules lying closer to the surface exhibit partial filling of the lowest unoccupied molecular orbitals due to charge transfer from the substrate, whereas those located further away remain electronically decoupled, as evidenced by spectroscopic data and supported by density functional theory calculations. These findings demonstrate that imide substitution can conveniently be exploited for modulating the interfacial electronic character of PDI molecules within a single-component self-assembly, since steric effects can modify molecular packing, adsorption height, and molecule–substrate coupling. Our results highlight that substrate-mediated charge transfer remains a critical design parameter for optimizing charge dynamics in application-specific organic sensitized heterostructures.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"13 18","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.70637","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149029122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fibroin dispersed within the PCL matrix was found to modulate crystalline organization, inducing distinct morphological transformations. The structural and morphological changes were comprehensively characterized using wide-angle X-ray scattering (WAXS), atomic force microscopy (AFM), optical microscopy, and scanning electron microscopy (SEM). Low fibroin concentrations in the blends (<50% w/w) promoted the formation of ring-banded PCL spherulites, whereas higher fibroin content (>50% w/w) resulted in the emergence of pits and porous surface topography. Despite the significant morphological changes on the blends’ surface, the type of PCL-crystallinity remained unchanged, as shown by WAXS. Furthermore, the evaporation rate of the solvent during processing critically influences the texture patterns of the films and the printed grids.

Extracellular vesicles (EVs) are emerging as promising cell-free therapeutics for tissue regeneration. However, their clinical translation remains limited by low yield and variable bioactivity. This study investigates how dynamic mechanical loading regulates the production, composition, and function of meniscus fibrochondrocyte-derived EVs (MFC-EVs). Using a custom bioreactor system, cells are subjected to physiologically relevant cyclic tensile loading. Mechanical stimulation significantly increases EV production, likely through the ESCRT-independent pathway, without altering vesicle size or tetraspanin expression. “Mechanically primed” EVs enhance aggrecan expression in recipient mesenchymal stromal cells (MSCs), mirroring the loading-response phenotype of their source cells. Proteomic profiling identifies 380 unique proteins across all EV groups, with primed EVs enriched in extracellular matrix- and cytoskeleton-associated proteins, along with pathways related to tissue morphogenesis, cell migration, and cartilage development. Together, these findings show that physiologic mechanical loading enhances MFC-EV yield and is associated with distinct EV cargo profiles and recipient MSC gene expression responses.

We performed quantitative proteomic analysis (nano LC-MS/MS) of proteins adsorbed from human serum onto six model organic surfaces. Identifying over 200 proteins per surface, we found that conventional predictors, such as isoelectric point and molecular weight, failed to explain selective enrichment on non-fouling films. Statistical analysis of surface amino acid compositions revealed that arginine uniquely distinguishes enriched from diluted proteins (p = 0.005; Bonferroni-corrected p = 0.125 over 25 structural descriptors, consistent with a correlation rather than a significance-corrected effect at the α = 0.05 level). We propose, but do not yet establish causally, that surface-exposed arginine residues, via their chaotropic guanidinium groups, may contribute to the local disruption of the protective hydration layers of anti-fouling coatings, thereby facilitating protein accumulation through enhanced protein–surface and protein–protein interactions.

However, their integration into electronic devices remains challenging, especially in forming uniform 3D thin films. Here, we present a versatile strategy for the layer-by-layer (LbL) growth of a conductive MOF film, copper hexaiminotriphenylene (CuHITP), onto a 3D laser-induced graphene (LIG) scaffold. The LIG template, prepared by femtosecond laser irradiation of polyimide, provides a hierarchical macroporous structure that increases the accessible surface area for MOF nucleation and bioreceptor immobilization. The resulting CuHITP layer conformally replicates the LIG structure while maintaining extended π-conjugation and high conductivity. When integrated into an extended-gate field-effect transistor (EG-FET), the CuHITP/LIG hybrid enables sensitive cortisol detection. By exploiting both the amine functionalities and unsaturated metal sites of the MOF framework, we achieve stable covalent and coordination-based immobilization of thiolated aptamers. The sensor exhibits a wide detection range from 1 pM to 10 µM in diluted buffer and retains sub-picomolar sensitivity in artificial sweat. This work highlights a robust approach for integrating c-MOFs into electronic biosensors and advances the development of non-invasive health-monitoring platforms.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"13 17","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.70620","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148904229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
