Peptide-based materials have the ability to encode necessary information to address geometrical parameters and control the physical/chemical properties of the assembled structure. Various approaches have been reported to induce specific peptide sequences into nano structures such as nanowire, nanotube, nanosphere and nano-sheet or film. Recently, we demonstrated that tyrosine-rich peptide (TRP) mediated 2D structure fabricated in air-water interface could be used as a bio-inspired catalyst scaffold. However, detailed studies for controlling morphologies of the assembled TRP have yet to be conducted. To induce the TRP into various structures in large scale, a solvent based fabrication method has to be developed. From the preliminary experimental results, we found that structural transitions of self-assembled structures were observed depending on the ratio and polarity of solvents. We confirm that the solvent environment for controlling non-covalent interaction such as hydrogen bonding and pi-pi stacking is important parameters on self-assembling process of TRP. |
