Controlled arrays of self-assembled peptide nanostructures in solution and at interface.
2013
Controlling the formation of large and homogeneous arrays of bionanostructures through the self-assembly approach is still a great challenge. Here, we report the spontaneous formation of highly ordered arrays based on aligned peptide nanostructures in a solution as well as at an interface by self-assembly. By controlling the time and temperature of self-assembly in the solution, parallel fibrous alignments and more sophisticated two-dimensional “knitted” fibrous arrays could be formed from aligned rod-like fibers. During the formation of such arrays, the “disorder-to-order” transitions are controlled by the temperature-responsible motile short hydrophobic tails of the gemini-like amphiphilic peptides (GAPs) with asymmetric molecular conformation. In addition, the resulting long-range-ordered “knitted” fibrous arrays are able to direct mineralization of calcium phosphate to form organic–inorganic composite materials. In this study, the self-assembly behavior of these peptide building blocks at an interface...
