20.500.12556/RUL-181648 Gold nanoparticle-embedded cellulose acetate structural, optical, mechanical, and cytotoxicity assessment The development of composites with embedded gold nanoparticles (Au NPs) and biopolymeric matrices, such as cellulose acetate (CA), has gained significant attention due to their unique synergistic properties, including enhanced mechanical, physical, and thermal characteristics. In this study, a composite material consisting of Au NPs embedded in a CA matrix was prepared and thoroughly characterized and its cytotoxicity evaluated for potential medical applications such as drug delivery, biosensing, and imaging. The composite was prepared using a newly developed in situ method, ensuring mostly uniform dispersion of Au NPs within the CA matrix. Various characterization techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM), energy-dispersive X-ray spectroscopy (EDX), X-ray photoelectron spectroscopy (XPS), UV-Vis spectroscopy, Fourier transform infrared spectroscopy (FTIR), dynamic mechanical analyses (DMA), thermogravimetric analysis (TGA), and cell viability assay were employed to evaluate the structural, mechanical, thermal and biocompatibility properties of the as-prepared composite. The obtained results indicate that even a miniscule content of Au NPs (<0.14 wt%) within the CA matrix can significantly change the properties of such composites. The produced materials are compact, flexible, strong, and exhibit low cytotoxicity, making them suitable for a wide range of potential applications. gold nanoparticles cellulose acetate composite materials in situ synthesis characterization techniques biocompatibility zlati nanodelci celulozni acetat composite materials in situ sinteza tehnike karakterizacije biokompatibilnost true false true Angleški jezik Slovenski jezik Članek v reviji 2026-04-10 13:18:49 2026-04-10 13:18:50 2026-04-13 04:41:56 0000-00-00 00:00:00 2026 0 0 Str. 798-812 iss. 2 Vol. 7 26 Jan. 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 661.728.82:620.3 2633-5409 10.1039/D5MA00764J 262569987 RAZ_Mustapic_Mislav_2026.pdf RAZ_Mustapic_Mislav_2026.pdf 1 1EA49BBE1224FB7A5A3AD668BD20ACF3 34ad283a6168e60c92cef711dde3545e382802d218955fbb87e98c609b36a62e 516a8a1d-34cf-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=232295 https://pubs.rsc.org/en/content/articlelanding/2026/ma/d5ma00764j 1 d829fe20-34ce-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=232294 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
