Activity of the carbodiimide coupled catalase to GNPs increases with increasing concentrations of catalase until apparent saturation is reached.
(Chirra et al. Catalase coupled gold nanoparticles: Comparison between carbodiimide and biotin-streptavidin methods)
| Concn. of Catalase used | Catalase Activity (μU)/GNP |
|---|---|
| 10 μM (no EDC added inactive GNPs; control) | ~0.02 |
| 0.01 μM | 0.4 |
| 0.1 μM | 7 |
| 1 μM | 93 |
| 5 μM | 125 |
| 10 μM | 131 |
