However, conventional enzyme-linked immunosorbent assay (ELISA) workflows are laboratory dependent, and disposable electrochemical sensors must reconcile efficient charge transfer with stable biorecognition to support reliable serological analysis. Here, a screen-printed carbon electrode (SPCE) was modified with chitosan-functionalized nitrogen-doped graphene (N-Gr/CS) and electrodeposited gold nanoparticles (AuNPs) to construct an AuNPs/N-Gr/CS/SPCE platform for dual-mode determination of adenovirus-associated immunoglobulin G (AdV-IgG). Material and electrochemical characterization verified stepwise interface assembly and progressive enhancement of interfacial charge transfer. Scan-rate and kinetic analyses indicated adsorption-dominant redox behavior with a diffusion contribution. Under optimized conditions, the platform exhibited logarithmic concentration–response relationships in both electrochemical impedance spectroscopy (EIS) and differential pulse voltammetry (DPV). DPV achieved a linear range of 5 ng mL^-1 to 1 mg mL^-1 with a limit of detection of 3.45 ng mL^-1, whereas the corresponding EIS values were 500 ng mL^-1 to 8 mg mL^-1 and 8.01 ng mL^-1. The sensor demonstrated acceptable repeatability, inter-sensor reproducibility, and tolerance to the interferents tested. In 10-fold diluted healthy human plasma spiked with AdV-IgG, recoveries of 95.8-104.2% and agreement with ELISA at the tested spike levels supported analytical feasibility in a simplified biological matrix. Collectively, these findings establish an interfacial design strategy for dual-mode serological analysis; clinical diagnostic performance was not assessed and will require validation in adequately powered, virologically characterized cohorts of adenovirus-positive and adenovirus-negative subjects.</p></div>","PeriodicalId":665,"journal":{"name":"Journal of Solid State Electrochemistry","volume":"30 10","pages":"3585 - 3599"},"PeriodicalIF":3.1,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148986137","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hybrid model is developed based on the competition pathways. Over the parameter ranges investigated (pH 5–9, 270–310 K, 0-0.5 M glucose), the hybrid method shows 20% greater performance than DET. MET pathways help the hybrid system exhibit a lower-activation energy route. The Hybrid model accounts for the competing reaction channels between DET and MET at the enzyme re-oxidation step. The hybrid model shows reasonable agreement with experimental data, yielding R² = 0.977 for the polarization curve and R² = 0.873 for concentration dependence.

In this work, poly(vinylidene fluoride) and poly(ethylene oxide) are investigated as binders for a P2-Na_2/3Mn_2/3Fe_1/3O₂ cathode material, with poly(ethylene oxide) selected as a fluorine-free alternative to poly(vinylidene fluoride) due to its favorable ionic conductivity, mechanical properties, affordability, and environmental compatibility, thereby enabling a systematic comparison between fluorinated and fluorine-free binders.

X-ray Photoelectron Spectroscopy analysis confirmed the chemical and electrochemical stability of poly(ethylene oxide), while NaF formation provided clear evidence for poly(vinylidene fluoride) defluorination and its further degradation during cycling.

Potentiodynamic polarisation measurements show that cPEN-treated Ti (PEN Ti) exhibits the lowest corrosion current density (4.18 μAcm⁻²) and passive current density (45.08 μAcm⁻²) at 0.6 V under simulated PEMFC cathodic conditions compared to bare Ti, and annealed PEN Ti (A-PEN Ti). Electrochemical impedance spectroscopy at 0.6 V reveals enhanced corrosion resistance for the bare Ti. Mott–Schottky analysis reveals variations in defect distribution, with PEN Ti exhibiting a lower donor density compared to both bare and A-PEN Ti. Post-annealing enhances the long-term passivation behaviour of the cPEN-treated sample during potentiostatic polarisation. Bare Ti performs better in the PEMFC environment owing to its compact passive layer and its defect structure.

This review therefore discusses charge transfer mechanisms, interface engineering methods, and the influence of material properties in a semiconductor heterojunction to give a systematic basis of design of PEC materials. Semiconductor heterojunctions are formed by the combination of two semiconductors with different energy levels to enhance the charge separation efficiency and to minimize the recombination of photogenerated electron-hole pairs. These structures operate based on the utilization of built-in electric fields at the heterojunction interface that in turn increases redox activity thus facilitating the degradation of organic contaminants.
