Rigid structure

8. Conclusion:
Very large complexes of triazine dendrimers and azobenzene chromophores are able to undergo mass transport and form SRGs under illumination.
This concept has been applied, for the first time, to induce surface patterns in a film of an azobenzene-functionalized native protein.
The azo-based topographical patterning could be combined with intrinsic capability of aFT to host other materials inside the protein cage, e.g., to produce surfaces for guided cell growth with both chemical and physical cues.
