Figure 7
(a) X-ray tomogram of SBA-15 1:1 showing clusters with different morphologies than observed for smaller ratios of HBsAg to SBA-15, obtained using the X-ray mCT setup. (b) Neutron tomogram of the SBA-15 1:1 sample showing clusters assigned to HBsAg with the same shape observed with X-rays, obtained with the CONRAD instrument. (c) 3D visualization of HBsAg aggregates in the SBA-15 1:1 sample. Each aggregate is shown with a different colour. These aggregates have a plate shape which is not observed in any other SBA-15 to HBsAg ratios. (d) 3D visualization of the SBA-15 particle using ID16B setup. The silica rods and some larger macropores can be observed, as indicated by the arrow (white region).
