Building upon a decade of our groups research and incorporating new experimental insights, this work presents a synthesis of VACNF performance as bioelectrodes, revealing a key unifying factor: the length of the VACNFs. Our analysis spans multiple dimensions—physicochemical properties, electrochemical behavior, and biological interactions—demonstrating how this single parameter plays a fundamental role across all aspects critical to the successful implementation of VACNF-based biosensors. We explore the impact of adhesion layers and catalyst metals on VACNF growth, influencing their macro- and nanoscale morphology. We further examine how macroscopic features such as density and alignment affect electroanalytical performance, particularly in terms of sensitivity and selectivity. Additionally, we investigate the nanoscale characteristics of VACNFs and their role in detecting key biomolecules, including dopamine, ascorbic acid, and uric acid. Beyond electrochemistry, we discuss how VACNFs facilitate neural cell guidance, underscoring their significance in neural interfacing and biomedical applications. Through this comprehensive synthesis, we identify VACNF length as a decisive factor that transcends chemistry, electrochemistry, and biocompatibility—serving as a fundamental variable for optimizing VACNF-based biosensors. This new perspective provides a straightforward and powerful approach to enhancing biosensor performance, offering a unifying principle that streamlines future research and application development.</div></div>","PeriodicalId":11266,"journal":{"name":"Diamond and Related Materials","volume":"155 ","pages":"Article 112261"},"PeriodicalIF":4.3,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143759195","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}

In this study, graphene quantum dots (GQDs) derived from olive pomace were synthesized via a simple hydrothermal method and decorated with iron oxide nanoparticles (Fe₃O₄) to form GQDs@Fe₃O₄ nanocomposites for malathion removal from environmental water. The physicochemical properties of these nanocomposites were characterized using SEM, FTIR, XRD, UV–Vis spectroscopy, and nitrogen adsorption-desorption techniques. The adsorption efficiency of the synthesized adsorbent was evaluated by measuring its adsorption capacity and removal efficiency, considering various parameters such as initial pH, initial concentration, temperature, adsorbent dosage, contact time, and salt concentration. Adsorption behavior was analyzed using kinetic and isothermal models, revealing that the Freundlich isotherm (R² = 0.9996) and the pseudo-first-order kinetic model (R² = 0.9998) provided the best fit for the malathion adsorption process. Under optimal conditions (5 mg L⁻¹ malathion, 30 mg adsorbent, 210 min), a maximum removal efficiency of 87.19 ± 4.47 % was achieved at 298.15 K, increasing to 97.24 ± 2.19 % at 323.15 K. When applied to real water samples from river and dam sources, the nanocomposites maintained a removal efficiency of 73–67 %, demonstrating their practical applicability. FTIR analysis confirmed the presence of malathion on the adsorbent surface post-adsorption, providing insights into the adsorption mechanism, which was further investigated through theoretical calculations.
