In this study, we introduce a straightforward method to evaluate the concentration of lactic acid (LA) in culture media using screen-printed electrode (SPE) and a microfluidic device. Standard SPEs were modified via electrochemical reduction of graphene oxide (GO) and deposition of nickel oxide (NiO) nanoparticles within a microfluidic device. Then, they could be used for the LA monitoring on-a-chip over a broad range (0.1–30 mM) with a low detection limit (0.05 mM) as well as the Electrochemical Impedance Spectroscopy (EIS) of the system. The modified SPEs were characterized by Scanning Electron Microscopy (SEM) to show the morphological changes of the electrodes and clarify the mechanism of the quality improvement. Finally, the modified SPEs were used to measure LA concentrations of organoid suspension culture media.

To address this issue magnetic iron oxide (Fe₃O₄) nanoparticles are promising eletrode materials owing to their high catalytic activity, easy synthesis procedure, lower cost and non toxic nature. Therefore, in the present work, we have investigated, a novel electrochemical sensor which is based on a screen printed carbon electrode (SPCE) modified with quercetin (Qr) functionalized-iron oxide nanoparticles (Qr-Fe₃O₄/SPCE) for the simultaneous voltammetric detection of Dop and Uric. The SEM analysis confirmed the porous morphology with nanosize distribution and XRD revealed the cystalline strucutre. The average size of the bare Fe₃O₄ and Qr-Fe₃O₄ nanoparticles were estimated to be 11.7 and 9.1 nm, respectively. The FT-IR analysis confirmed the successful functionalization of quercetin on the surface Fe₃O₄ nanoparticles. The cyclic voltammetric and electrochemical impedance spectroscopic techniques were used to characterize the electrical properties of the electrodes. The Qr-Fe₃O₄ sensor greatly improved the peak current signals towards the oxidation of Dop and Uric which was found to be due to the synergistic electrocatalytic effect of Qr and Fe₃O₄ nanoparticles on the electrode surface. The fabricated sensor presented linear peak current responses as a funtion of Dop and Uric concentrations in the ranges from 0.2 – 50 µM and 0.2 – 25 µM, with detection limits of 0.07 and 0.08 µM, respectively. Moreover, the Qr-Fe₂O₃/SPCE based sensor showed good repeatability with RSD of 1.7% for Dop and 2.8% for Uric and displayed good discrimination ability over the common interferents. The successful application of the sensor to the spike urine samples enabled the determinations with good recoveries without matrix effect from urine sample. Thus the developed electrochemical sensor could be a suitable sensing device for Dop and Uric with a large peak potential separation ability due to its easy preparation procedure, ecofriendly nature, lower cost and good sensitivity and selectivity.</div></div>","PeriodicalId":18265,"journal":{"name":"Materials Research Bulletin","volume":"185 ","pages":"Article 113317"},"PeriodicalIF":5.3,"publicationDate":"2025-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143104488","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}
