Designing smart biomaterials presents challenges in predicting self-assembly and environmental responsiveness. Peptides offer a promising solution due to their well-understood folding and tunable chemistry for creating advanced biomaterials.

Area of Science:

  • Biomaterials Science
  • Supramolecular Chemistry
  • Nanotechnology

Background:

  • Designing biomaterials requires predicting large-scale self-assembly from atomic interactions and achieving environmental responsiveness, termed 'smartness'.
  • Recent technological advances, particularly in imaging, have enabled new applications for peptides in biomaterials.
  • Peptides are attractive due to predictable folding into specific structures and versatile chemistry for functional manipulation.

Purpose of the Study:

  • To explore the potential of peptides as advanced biomaterials.
  • To highlight the 'smartness' of peptide-based materials through environmental responsiveness.
  • To discuss the advantages of using peptides in biomaterial design.

Main Methods:

  • Review of current literature on peptide self-assembly and biomaterial applications.
