Peptide-derived coordination frameworks for biomimetic and selective separation

Area of Science:

• Analytical Chemistry
• Materials Science
• Biochemistry

Background:

• Peptide-derived metal-organic frameworks (PMOFs) are biomimetic materials integrating peptides into metal-organic frameworks (MOFs).
• The incorporation of peptides imparts unique properties like conformational flexibility, guest adaptability, chirality, and molecular recognition.
• These properties enhance the performance of PMOFs in various separation applications.

Purpose of the Study:

• To review recent advances in the engineering and applications of PMOFs for selective separation.
• To discuss the biomimetic size-, enantio-, and affinity-selective separation performances of PMOFs.
• To summarize the applications of PMOFs in adaptive separation, chiral separation, and affinity isolation.

Main Methods:

• Review of recent literature on PMOFs.
• Analysis of chemical structures and functions of MOFs and peptides in PMOFs.
• Discussion of separation mechanisms and performance metrics.

Main Results:

• PMOFs demonstrate significant potential in enantiomeric and affinity separation due to peptide incorporation.
• Applications include adaptive separation of small molecules, chiral separation of drugs, and isolation of bioactive species.
• PMOFs exhibit unique size-, enantio-, and affinity-selective separation capabilities.

Conclusions:

• PMOFs represent a promising class of materials for selective separation in analytical and bioanalytical chemistry.
• Further research into PMOFs holds potential for addressing challenges in complex biosample separation.
• Continued development is crucial for realizing the full capabilities of PMOFs in advanced separation technologies.
