Key Findings
- 01BSA adsorption capacity increased with BSA concentration, reaching 0.045 mg/cm2 at 10 mg/mL BSA, indicating good biocompatibility.
- 02Oxygen and nitrogen permeability was 5 Barrer, while carbon dioxide permeability ranged from 26 to 37 Barrer.
- 03Oxygen transmissibility was sufficient for wound dressing applications, though on the lower end for daily wear contact lenses.
- 04Drug permeability ranged from 0.8 – 4.3 x 10-7 cm2/s, and diffusion coefficients were approximately 1.8 x 10-9 cm2/s (sorption) and 0.8 – 2.7 x 10-9 cm2/s (desorption), showing potential for controlled release.
