Tyrosine based ultrathin 2D peptide structure at air/water interface |
| 초록 |
We systematically introduced repeating tyrosine units into peptides of various lengths to study the influence of the peptide sequence on self-assembly. We found that specific sequences of tyrosine containing peptides can give densely packed 2D film structure at air/water interface and the resulting structure can withstand the large surface tension of water and modify the intrinsic curvature of water droplet. The atomic force microscopy (AFM) analysis shows the evidence of film stacking of multiple nano sheets, whoes minimum thickness is 1.4 nm. The peptide film provides a tunable platform to template 2D hybrid materials. Thus, highly ordered 2D assemblies of polypyrrole that cannot be formed using conventional methods were created for the first time. |
