20.500.12556/RUL-153126 Tuning mechanical characteristics and permeability of polyvinyl alcohol-alginate hydrogels by natural deep eutectic solvents addition research data underlying the article Enzyme entrapment in porous hydrogel structures by cross-linking different (bio)polymers is one of the simplest and non-invasive techniques to immobilize biocatalysts. Hydrogels should provide specific attributes in order to be suitable matrices for enzyme immobilization, e.g. favorable pore size and stability in the reaction solvent. The addition of polyvinyl alcohol to the copolymeric hydrogel resulted in improved shear modulus by threefold while also improving chemical resistance to high pKa environment ((S)-α-Methylbenzylamine). On the other hand, hydrogels typically have poor permeability for typical substrates in industrial biocatalysis with low water-solubility. To address this challenge, a selected natural deep eutectic solvent was added during polyvinyl alcohol-alginate copolymeric hydrogel preparation. Permeability to ethyl 3-oxobutanoate, a model molecule used for bioreduction to chiral alcohols in yeast cells, and the rheological properties of hydrogels with added amounts of eutectic solvents was measured. The addition of 20 % of the natural deep eutectic solvent (NADES) to the mixture for the preparation of the hydrogel increases the volume of the resulting hydrogel and subsequently also its permeability to ethyl 3-oxobutanoate, while decreasing the Shear modulus. hydrogel natural deep eutectic solvent polyvinyl alcohol alginate rheology permeability hidrogel naravna globoka evtektična topila polivinilalkohol alginat reologija prepustnost true false false Angleški jezik Slovenski jezik Neznano 2023-12-18 22:13:21 2023-12-18 22:13:28 2025-04-16 13:05:53 0000-00-00 00:00:00 2023 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 Expdata_-_rheology.ods Expdata_-_rheology.ods Expdata_-_rheology.ods 1 6F168FB04F5CE9A2C13ED991C0C19EE5 af7bd356d5861604a34f4d2a69883deae4b0eae9b1595c0a2a1cda5bd06b54d8 700e01eb-9deb-11ee-a59a-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=179023 diffusivity_exp_data.pdf diffusivity_exp_data.pdf diffusivity_exp_data.pdf 1 DBE5679CF91B982CEF38E36868F9A3E6 fe5d83b4fb3c82dc83c17bcdc2494e5f4653bc12a995185d77cb19d0c979703c 7b09f297-9deb-11ee-a59a-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=179024 Fakulteta za kemijo in kemijsko tehnologijo Meritve in testi 0 0 0
