Supplementary Information SANS of dry carbons C1 and C2, and protein distribution inside them. a) SANS measurements of the dry carbons The differences in structure between the two dry samples C1 and C2 are illustrated by their SANS responses shown in Figure S1. In C2, the increased I(q) intensity in the region Å-1 is the signature of its higher micropore content. In q>0.1 C1, the knee in the spectrum of at Å-1 defines the resolution threshold below q≈0.03 which the micropores become too small to be detected and only large scale, low density, averages can be seen. The insets in Figure S1 show the Porod scattering regime in the high range where the intensity varies as q (S1) I(q)=q-4+b which determines the internal surface area of the carbon samples, [S1].
