An Obstruction-Scaling Model for Diffusion in Homogeneous Hydrogels
Abstract
A mathematical description of the restricted movement a solute experiences while diffusing in a homogeneous hydrogel is presented. The model is based on the premise that physical obstruction effects dominate the diffusive process, and a scaling law expression is incorporated to describe the distance between cross-links in the polymer network. The model was compared to experimental data taken from literature sources and found to provide good agreement to the effects of both polymer volume fraction and solute size on the diffusivity of a solute within the hydrogel.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
