20.500.12556/DKUM-88499 The synthesis, surface analysis, and cellular response of titania and titanium oxynitride nanotube arrays prepared on TiAl6V4 for potential biomedical applications Titania nanotubes are gaining prominence in the biomedical field as implant materials due to their mechanical durability, nano-rough properties, and positive influence on cellular response. This work aimed to synthesize titania and titanium oxynitride (TieOeN) nano- tubular arrays on TiAl6V4 substrates using an anodic oxidation process followed by annealing in air or by additional nitridation in NH3 atmosphere. Different nanotubular layers of unique morphology and structure were fabricated and investigated using advanced surface analysis and biocompatibility tests. In-depth surface analysis was per- formed by field emission scanning electron microscopy (FE-SEM), atomic force microscopy (AFM), 3D profilometry, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and time-of-flight secondary ion mass spectroscopy (ToF-SIMS). Cell testing using adipose- derived mesenchymal stem cells and human fetal osteoblasts demonstrated good cell viability, high proliferative capacity, and a favorable overall effect on cell morphology for the TieOeN nanotubes. surface analysis XPS AFM tandem ToF-SIMS titania nanotubes Ti-O-N nanotubes anodization true false true Brazilian Metallurgical Materials and Mining Association, Elsevier Angleški jezik Angleški jezik https://www.sciencedirect.com/journal/journal-of-materials-research-and-technology Članek v reviji 2024-05-07 10:13:21 2024-05-07 10:13:22 2024-05-08 03:18:34 0000-00-00 00:00:00 2023 0 0 str. 4074-4090 Vol. 24 May-June 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2023-01-28 2023-04-04 2023-04-09 543.2 151362051 10.1016/j.jmrt.2023.04.021 2214-0697 1-s2.0-S2238785423007147-main.pdf 1-s2.0-S2238785423007147-main.pdf 1 E052EA33AF66C6F685979FB62E7147D2 3a90adc61d8f53d5dcfbf598648dc4aea351b79937d9fa2ad30061bb3e58aef7 57897e11-0c4a-11ef-a864-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=179054 https://www.sciencedirect.com/science/article/pii/S2238785423007147?via%3Dihub 0 620e0823-0c4a-11ef-a864-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=179055 Fakulteta za kemijo in kemijsko tehnologijo Medicinska fakulteta 0 0 0
