Advanced materials that have controllable pH-responsive properties when submerged in the lysosome have a great potential in intracellular drug delivery. We developed novel poly(L-amino acid) nanogels that were prepared by a facile cross-linking of poly[L-aspartic acid-g-(3-diethylaminopropyl)]-b-poly(ethylene glycol)-maleimide [poly(L-Asp-g-DEAP)-b-PEG-Mal] and poly(L-aspartic...

A mineral (calcium phosphate, CaP)-reinforced core-shell-corona micelle was evaluated as a nanocarrier of doxorubicin (DOX) for cancer therapy. The polymer micelles of poly(ethylene glycol)-b-poly(L-aspartic acid)-b-poly(L-phenylalanine) (PEG-PAsp-PPhe) in the aqueous phase provided the three distinct functional domains: the hydrated PEG outer...

A novel block copolymer containing two polymeric components, poly(L-aspartic acid)-b-poly (L-phenylalanine) (PAA-PPA), was synthesized and its potential for the preparation of copolymer micelles with a poorly water-soluble drug was investigated in this study. The chemical structure and physical properties of...

We report in this communication a simple, facile surface modification strategy to transfer hydrophobic manganese oxide nanoparticles (MONPs) into water by using polyaspartic acid (PASP). We systematically investigated the effect of the size of PASP-MONPs on MRI of normal liver...
