  • To discuss the properties and biomedical applications of protein/peptide-based hydrogels.

Main Methods:

  • Literature review of protein and peptide hydrogels.
  • Analysis of various peptide/protein structures (β-hairpin, α-helical coiled coil, elastin-like, silk fibroin, resilin).
  • Description of gelation mechanisms, physical, chemical, mechanical properties, and biocompatibility.

Main Results:

  • Diverse protein and peptide hydrogels have been designed with tunable properties.
  • These hydrogels exhibit structural and mechanical similarities to the native ECM.
  • Protein/peptide hydrogels demonstrate excellent biocompatibility and potential for bio-functionalization.

Conclusions:

  • Protein- and peptide-based hydrogels are versatile biomaterials for biomedical applications.
