| abstract |
The invention provides metal-chelating poly (ether amide) polymers useful in preparation of polymer compositions for delivering a variety of cargo molecules, such as bioactive agents. In solution metal ions and cargo molecules, such as vaccine epitopes, that include metal avid amino acids can be loaded into the polymer compositions and held in a non-covalent complex. Nanoparticles of such polymer compositions can also be prepared directly from the solution. |
