Additionally, hydrogel density and conformation of proteins should really also not be excluded. Release data plotted like a function of the square root of time showed that the diffusion mechanism of every one of the four model proteins is biphasic. The initial Molecules 2021, 26, 873 linear component indicated diffusion-controlled release while deviation through the straight line at longer instances could possibly be linked with anomalous diffusion.13 ofFigure 7.
