Abstract	A mathematical description of the restricted movement a solute experiences while diffusingin a homogeneous hydrogel is presented. The model is based on the premise that physical obstructioneffects dominate the diffusive process, and a scaling law expression is incorporated to describe the distancebetween cross-links in the polymer network. The model was compared to experimental data taken fromliterature sources and found to provide good agreement to the effects of both polymer volume fractionand solute size on the diffusivity of a solute within the hydrogel.
