Peptide-based porous materials and their applications

The porous structure formed by the self-assembly of peptides is a new generation of porous materials with potential applications in the fields of catalysis, sensing, separation, and drug delivery. The pores of the material are filled with amino acid side chains, so the pore size and properties of the peptide-based porous material can be adjusted by rational design or modification of the peptide sequences. The introduction of functional moieties and metal ions has expanded the range of peptide-based porous materials. This review covers the design, synthesis, self-assembly, and properties of peptide-based porous materials, and summarizes their applications in different fields in recent years.
