Percent of SNAP remaining in films (initially prepared with 10 wt% SNAP) after various durations of soaking in 4 mL PBS in the dark at room temperature, 22°C (A), or 37°C (B). Data is based on the difference between the amount of SNAP that leached from various polymers into the PBS, as monitored at 340 nm, and the initial amount of SNAP doped in the film. Data is the mean ± SEM (n=3).
