Objective- Mimic Stomach Acid environment to verify that hydrogel core will dissolve without liposome shell - Swelling Study of pure hydrogels in water Procedures1) Prepare several different low pH solutions (1.5 , 2.5, 3.5) using milli Q H2O and 1N Hydrochloric Acid Data
Observations-22,000 g/mol PVOH did not form a hydrogel. After three freeze thaw cycles (24 hours @ -20°C, 24 hours at room temperature) the sample was still very much a liquid. This being said, we have concluded this molecular weight is not suitable for our drug delivery system.
