20.500.12556/RUL-137871 Protein release from nanocellulose and alginate hydrogels the study of adsorption and desorption kinetics This work presents a study of the lysozyme release from crosslinked TEMPO nanocellulose (TOCNF) and alginate (ALG) hydrogels in a medium with different ionic strength and temperature. The main objective is to develop a mathematical model for a detailed study of the concurrent action of diffusion mechanism and adsorption/desorption kinetics. Model fit parameters provide important information about the initial (maximum) adsorption rate and its deceleration with increasing ionic strength of the release medium. Similarly, the initial (minimum) desorption rate and its acceleration with increasing salt concentration can be determined. The model leads us to the conclusion that the initial adsorption rate is higher in the case of TOCNF, but due to fewer electrostatic interactions and morphology as well as topography of the surface, it decreases to a negligible value much faster than in the case of ALG, where the diffusion process becomes dominant. lysozyme adsorption TEMPO nanocellulose alginate controlled protein release mathematical modeling lizocim adsorpcija TEMPO nanoceluloza alginat kontrolirano sproščanje proteina matematično modeliranje polimeri true false true Angleški jezik Slovenski jezik Članek v reviji 2022-07-05 03:41:20 2022-07-05 10:00:38 2022-09-15 04:15:58 0000-00-00 00:00:00 2022 0 0 10 str. art. 112677 Vol. 217 1 Sep. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 678:544.4 0927-7765 10.1016/j.colsurfb.2022.112677 113668355 1-s2.0-S0927776522003605-main.pdf 1-s2.0-S0927776522003605-main.pdf 1 DE7CDCB15E6D0FCDEB54DCD51A0626BC 33ccb172fecb7c73814ed88699eb95e94c07b666edaca5f285c3ef153e7e080a 93e9fb03-fc37-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=157993 https://www.sciencedirect.com/science/article/pii/S0927776522003605 0 5b4d8159-fc03-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=157980 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
