Safety and photochemotherapeutic application of poly(γ-glutamic acid)-based biopolymeric nanoparticle

Acta Pharmaceutica Sinica B, 2019
The safety of nanomaterials, a crucial consideration for clinical translation, is enhanced by using building blocks that are biologically nontoxic. Here, we used poly(γ-glutamic acid) (γ-PGA) and dopamine as building blocks of polymeric nanomaterials for

Microbial synthesis of poly-γ-glutamic acid: current progress, challenges, and future perspectives

Biotechnology for Biofuels, 2016
Poly-γ-glutamic acid (γ-PGA) is a naturally occurring biopolymer made from repeating units of l-glutamic acid, d-glutamic acid, or both. Since some bacteria are capable of vigorous γ-PGA biosynthesis from renewable biomass, γ-PGA is considered a ...
