Activity of MnTBAP composite surfaces over time. The ability of anti-oxidative surfaces to prevent NBT reduction was measured up to two days after synthesis and incubation in PBS. Hybrid (composite) surfaces (red square) demonstrated an initial decline in NBT reduction activity, followed by low-level sustained activity. In contrast, surfaces with only conjugated MnTBAP maintained activity over time (blue circle). Data was normalized to soluble MnTBAP (0.24 µM). Grey region represents the working therapeutic range for resveratrol. Data is shown as an average ± s.e.m. N=3, n=9.
