(A) Diffusion of SNAP from 10 wt% SNAP-doped E2As films soaking in 1 mL PBS in the dark, as monitored at 340 nm, at room temperature (RT, 22°C) or 37°C. (B) Comparison of the cumulative SNAP leaching and cumulative NO release (based on NOA-based or SNAP-based NO release data) from the 10 wt% SNAP-doped E2As films soaking in PBS at 37°C in the dark. Nitric oxide release from SNAP-doped E2As films can occur from thermal and/or photochemical decomposition of SNAP within the polymer phase, or from SNAP that leached into the aqueous phase. For the SNAP-doped E2As films, approximately 27% of the total NO release is attributed to the SNAP leaching.
