Fabrication of Chiral Materials via Self‐Assembly and Biomineralization of Peptides

With different scales of chirality, chiral materials have various particular properties and potential applications in many fields. Peptides are the fundamental building units of biological systems, and a variety of ordered functional nanostructures are produced through self‐assembly and biomineralization of peptides in nature. This Personal Account describes chiral silica materials fabricated by using amphiphilic peptides as building blocks. Three particular biomineralization approaches are described based on different kinds of geometry of amphiphilic peptides: the influence of the specific amino acid proline in the peptide sequence, the hydrophilicity of amphiphilic peptides, and different kinds of hydrophobic tails in amphiphilic peptides. These strategies are useful for designing peptides toward the bottom‐up synthesis of nanomaterials as well as improving the understanding of the mechanism of peptide self‐assembly.
