by hydrogen bonds (Bodin etal. 2007b). Furthermore, the cellulose has shown good biocompatibility
(Helenius etal. 2006), but the degradability of the material needs to be further evaluated.
Figures 18.7b and c show SHG microscopy images measured on a cellulose tube in its natural state
without special sample preparation for microscopy. Detailed information on the morphology at a bril-
lar level can be seen in the close-up of Figure 18.7b whereas the montage of images in Figure 18.7c shows
a full radial prole of the tube presenting the morphology on a larger scale.
Figure 18.8 shows SHG images ...
