Nanostructured Amphoteric Poly(γ-glutamic acid)s: Preparation by Self- Complexation and Their Functions

摘要

We prepared a novel polyampholyte NPs by self-complexation of amphoteric poly (amino acid), without chemical cross-linking. The size and surface charge of the NPs can be regulated by grafting degree of the Arg. Moreover, the NPs showed various behaviors of the protein adsorption, leading to contribute to safe protein nanocarriers.
