| Outline of Final Research Achievements |
Advances in peptide self-assembly provide strong incentives to fabricate novel nanostructured biomaterials. In this study, novel intelligent hydrogels that show gel-to-sol transition in response to time under constant physical condition were fabricated through programmed peptide self-assembly. Three-armed collagen-mimetic short peptides (CMP) were newly designed and synthesized as building units for self-assembly. A detailed characterization of the CMPs was performed in water by CD, SEM, TEM, AFM and rheological measurements. By tuning the chain length and amino acid sequence, we could successfully obtain various CMP-based hydrogels with different lifetime of gel-state.
