Abstract
The relationship between the delivery of dexamethasone and the composition of silicone hydrogel materials was investigated. Two hydrophilic monomers (2-hydroxyethyl methacrylate or N,N-dimethylacrylamide), a siloxy methacrylate-based monomer (1-(Bis(trimethylsiloxy)methylsilyl)propoxy-3-metacryloxy-2-propanol, a polysiloxane (monomethacryloxypropyl-terminated polydimethylsiloxane) and a polymerizable silicone surfactant (Silmer ACR A008-UP) were used to synthesize silicone hydrogels of variable composition. The materials properties, such as surface wettability and equilibrium water content, were highly dependent on polymer composition. All dexamethasone-loaded hydrogels showed uptake that was driven primarily by sorption to the polymer phase. Furthermore, a positive correlation between loading mass and equilibrium water content was established. The duration of drug release from the hydrogels ranged from one to greater than two weeks depending on the monomer composition and relative contribution of hydrophilic and hydrophobic monomers. Higuchi model rate constants for the release showed strong correlation with the equilibrium water content, signifying that the release is likely controlled by aqueous phase diffusion.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
