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.

In contrast to conventional carbon nanotubes and fibers, the graphene layers are stacked perpendicular to the tube axis, while the size of the most common tube fibers can reach up to 10 μm in diameter and 100 μm in length. X-ray diffraction, Raman spectroscopy, scanning and transmission electron microscopy, small-angle X-ray scattering combined with complementary techniques have been used to characterize the structure of the glass-like carbon derived from furfuryl alcohol catalytically-graphitized using Si particles at 3000 °C. Since control of graphite shape is vital to achieving the level of performance required in contemporary applications, the obtained results demonstrate that the catalytic graphitization method may be employed to produce filamentous graphite crystals.</div></div>","PeriodicalId":11266,"journal":{"name":"Diamond and Related Materials","volume":"155 ","pages":"Article 112236"},"PeriodicalIF":4.3,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143785167","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}
