Electrochemical sensors are advantageous as a simple and portable technique. However, unmodified electrodes have limited active surface area, slow electron-transfer kinetics, low signal stability, and limited sensitivity and selectivity. Nanoparticle modification can overcome these limitations by increasing the number of active sites and enhancing charge transfer at the electrode-electrolyte interface. In this study, manganese oxide (MnO<ce:inf loc=\"post\">2</ce:inf>) nanoparticles were used because they have a high surface area, many oxygen-containing adsorption sites, strong affinity for heavy-metal ions, low toxicity, and low cost. However, MnO<ce:inf loc=\"post\">2</ce:inf> has low electrical conductivity that limits its electrochemical performance. To overcome this limitation, gold nanoparticles (AuNPs) were used with MnO<ce:inf loc=\"post\">2</ce:inf> to enhance conductivity, promote electrochemical activity, and improve signal enhancement. In addition, Nafion was added to improve the stability of the modified electrode. A Nafion/AuNPs–MnO<ce:inf loc=\"post\">2</ce:inf>/ITO electrode was fabricated using the drop-casting method and optimized by varying the MnO<ce:inf loc=\"post\">2</ce:inf> concentration and AuNP loading. The optimized Nafion/15µl AuNPs/4 MnO<ce:inf loc=\"post\">2</ce:inf>/ITO electrode simultaneously detected Cd(II), Pb(II), and Cu(II), with sensitivities of 1.6067, 3.1411 and 1.4897 µA ppb<ce:sup loc=\"post\">-1</ce:sup> and detection limits of 1.89, 1.10, and 2.89 ppb, respectively. The optimized electrode has two linear ranges (1–5 and 10–100 ppb) and successfully detected Cd(II), Pb(II), and Cu(II) ions in seawater samples. These results demonstrated that the Nafion/15µl AuNPs/4 MnO<ce:inf loc=\"post\">2</ce:inf>/ITO electrode provides high sensitivity and shows good potential for the simultaneous detection of heavy-metal ions in complex environmental samples.","PeriodicalId":305,"journal":{"name":"Electrochimica Acta","volume":"41 1","pages":""},"PeriodicalIF":6.6,"publicationDate":"2026-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149358719","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}

Herein, we report a Co@NCNT/ZC catalyst prepared by pyrolyzing ZIF-67 synthesized in the presence of graphene oxide (GO). The catalyst featured an electrochemically relevant architecture of Co nanoparticle (NP)-encapsulated nitrogen-doped carbon nanotubes (NCNTs) growing on the ZIF-67-derived carbonaceous particle (ZC) and intertwining neighboring ZC particles, forming a three-dimensional (3D) conductive network.

In response to the issues associated with traditional platinum electrodes in electrochemical DNA synthesis—namely high cost, poor compatibility with CMOS processes, and difficulties in high-density integration [<ce:cross-refs ref>1–4</ce:cross-refs>]—this paper evaluated candidate electrode materials for electrochemical DNA synthesis, including ruthenium (Ru) and titanium nitride (TiN), with Pt as the control, and validated the feasibility of ruthenium (Ru) as a CMOS-compatible alternative electrode material [<ce:cross-refs ref>5–7</ce:cross-refs>]. Electrochemical characterization revealed that TiN exhibited limited catalytic activity in the present system, whereas Ru displays kinetic performance similar to that of Pt (approximately 250 mV·dec⁻¹). Combining single-base fluorescence experiments, Fluorescence in situ hybridization experiments on 50-nt DNA sequences (20-nt target sequence for FISH probe binding), and synthesis and sequencing experiments on 80-nt DNA sequences, this paper suggests that Ru electrodes may serve as a promising alternative to Pt electrodes for electrochemical DNA synthesis. Among the tested conditions, at a current of 1400 nA per pixel, the Ru electrode achieved a sequence accuracy of 99.6% (supported by over one million high-quality sequencing reads), comparable to the performance of Pt.

In this work, we systematically investigated the electrochemical behaviour of commercial gold nanoparticles (AuNPs) with diameters ranging from 5 to 60 nm in the presence of L-Cysteine under biologically relevant conditions. Cyclic voltammetry was performed at 37°C across a pH range of 2.0-7.4 using AuNP-modified glassy carbon electrodes, while high-resolution mass spectrometry was employed to monitor cysteine oxidation and cystine (disulfide) formation. The voltammetric response showed a strong pH dependence, evolving from a sharp anodic peak at low pH to broad and poorly defined oxidation waves at neutral pH. In contrast, nanoparticle size primarily affected the position of the anodic feature, with smaller AuNPs exhibiting oxidation at lower potentials than larger particles. Conversion of peak potentials to the reversible hydrogen electrode scale revealed a non-Nernstian pH dependence, indicating that the anodic response was not governed by a simple proton-coupled Au oxidation process. Instead, the results suggest overlapping contributions from Au oxidation and dissolution, cysteine adsorption, cysteine-to-cystine oxidation, and the formation of mixed sulfur-containing surface species. These findings provide new insight into the environment-dependent electrochemical reactivity of Au nanomaterials and highlight the importance of interfacial chemistry in biologically relevant thiol-containing systems.","PeriodicalId":305,"journal":{"name":"Electrochimica Acta","volume":"18 1","pages":""},"PeriodicalIF":6.6,"publicationDate":"2026-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149358923","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}
