Abstract: γ-Polyglutamic acid is a kind of biomaterial and environmentally friendly polymer material
with the characteristics of water solubility and good biocompatibility. It has a wide range of applications
in medicine, food, cosmetics and other fields. This article reviews the preparation, characterization
and medical applications of γ-polyglutamic acid nanoparticles. Nanoparticles prepared by using γ-
polyglutamic acid not only had the traditional advantages of enhancing drug stability and slow-release
effect, but also were simple to prepare without any biological toxicity. The current methods of nanoparticle
preparation mainly include the ion gel method and solvent exchange method, which use the total
electrostatic force, van der Waals force, hydrophobic interaction force and hydrogen bond force between
molecules to embed materials with different characteristics. At present, there are more and more
studies on the use of γ-polyglutamic acid to encapsulate drugs, and the research on the mechanism of its
encapsulation and sustained release has gradually matured. The development and application of polyglutamic
acid nanoparticles have broad prospects.
