Self-assembly Peptide for Biomedicine Application

Peptide self-assembly is a popular phenomenon in nature.Peptide is an ideal biomaterial for its biocompatibility and controlled degradability.The key advantage of using peptide self-assembly is that building blocks self-associate in particular patterns to form higher order organized complexes which can be designed and engineered at the molecular level.Peptide self-assembly can be used in biomedicine.Recent years,peptide self-assembly is being researching in material sciencem,medicine and is applied as drug delivery system and tissue engineering scaffolds.This article focus on the basic principle of peptide self-assembly and its application in delivery carriers and scaffolds of tissue engineering.
