Figure 6: Influence of DNA on the enzymatic activity.

(a) Schematic of the distribution of positive ions near the surface of DNA origami. (b) pH-distance profile near the DNA origami. (c) pH-activity profile of GOx in 1 mM glucose and (d) pH-activity profile of HRP in 200 μM H2O2 and 2 mM ABTS. Error bars represent the s.d. of three replicates.
