Self-assembly of thermally responsive nanoparticles of a genetically encoded peptide polymer by drug conjugation

Angew Chem Int Ed Engl. 2013 Feb 4;52(6):1683-7. doi: 10.1002/anie.201200899. Epub 2012 Dec 20.

Abstract

Chimeric polypeptides (CPs) that are derived from elastin-like polypeptides (ELPs) can self-assemble to form nanoparticles by site-specific covalent attachment of hydrophobic molecules to one end of the biopolymer backbone. Molecules with a distribution coefficient greater than 1.5 impart sufficient amphiphilicity to drive self-assembly into sub-100 nm nanoparticles.
