Therefore, this work aimed to develop photoelectrochemical sensing and degradation of naproxen (NPX) using zinc-metal organic framework /graphitic carbon nitride thin film-based fluorine-doped tin oxide (Zn-MOF/g-C₃N₄/FTO) as anode material for the sensing and degradation of naproxen (NPX). The surface morphology, structure, surface property, surface area, optical property, photocurrent, and charge transfer kinetics abilities were studied using different techniques. The nanocomposites showed a superior photocurrent response (0.815 mA cm^-2) compared to the original g-C₃N₄ (0.328 mA cm^-2). The photo-anode made of Zn-MOF@g-C₃N₄/FTO displayed the highest photocurrent value, indicating that the alignment of the two semiconductor bands prevented the quick recombination of electron-hole pairs. Owing to these attractive features, the Zn-MOF/g-C₃N₄/FTO electrode was applied for photoelectrochemical detection of NPX using chronoamperometry. Interestingly, the nanocomposites-based FTO ascribed a lower detection limit (2.3 ng <span>l</span>^-1) with a wide linear range concentration of NPX (0.5 to 200 µg <span>l</span>^-1). Additionally, the analytical assessment of repeatability and reproducibility demonstrated robust performance, with commendable relative standard deviations (RSD%) of 2.54 % and 2.40 %, respectively. On the other hand, a remarkable degradation efficiency of 97.52 % was attained when employing a bias potential of 0.1 V during a 2 h photoelectrocatalytic oxidation of NPX. The degradation process was primarily driven by the active participation of holes and hydroxyl radicals in ring opening and subsequent cleavage of by-products. The notable effectiveness of this degradation can be attributed to the combined and synergistic effects of both electrochemical and photocatalytic degradation techniques. The current state demonstrates its effectiveness in the photoelectrochemical sensing and removal of NPX using MOF/g-C₃N₄ nanocomposites-based electrode materials in wastewater.</div></div>","PeriodicalId":436,"journal":{"name":"Talanta Open","volume":"10 ","pages":"Article 100371"},"PeriodicalIF":4.1,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142662698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rosuvastatin (ROS) is a statin drug used to prevent cardiovascular diseases and treat abnormal lipids. This study describes the design and fabrication of a nanomaterial-assisted molecularly imprinted polymer (MIP)-based electrochemical sensor for ROS determination. In addition, MIP-based electrochemical sensors were designed to detect ROS in both standard solutions and serum samples. In the MIP-based electrochemical sensor developed via the photopolymerization (PP) technique on the glassy carbon electrode (GCE) surface, were used zinc oxide nanoparticles (ZnO NPs) as a pore former, p-aminobenzoic acid (p-ABA) as functional monomer, ROS as template molecule. Electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV), and scanning electron microscopy (SEM) techniques were used to carry out detailed characterizations concerning surface morphology and electrochemistry. Under optimized experimental conditions, the linearity range of the designed sensor was found 1.0 × 10⁻¹³–1.0 × 10⁻¹² M. The superior selectivity of the MIP-based sensor against ROS in the presence of their binary mixtures was confirmed by interference studies. The recovery rates of the MIP-based sensors were calculated as 100.35 % and 99.16 % in commercial tablet form and serum samples, respectively. Moreover, the proposed sensor's relative selectivity coefficient (k′) was calculated, and it provided good selectivity for ROS over the NIP sensor. In conclusion, this newly developed sensor offers an advantageous approach for selective, sensitive, rapid and cost-effective analysis of ROS from binary mixtures.
