self-assembled nanoparticles of poly(amino acid)s and their secondary structure controls |
| 초록 |
PHEA containing amine group in the side chain was synthesized by aminolysis of PSI with 2-aminoethanol and 1,6-hexanediamine. PHEA-g-oligo(L-lysine) was successfully synthesized using living polymerization of α-amino acid-N-carboxyanhydrides. Self-assembled nanoparticles of PHEA-g-oligo(L-lysine) in an aqueous solution was fabricated. The morphology changes of self-assembled nanoparticles were induced by the pH or temperature-responsive conformational transition of specific poly (amino acid) group. The conformational transition of secondary structure of poly (amino acid) group was confirmed by CD (circular dichroism). The morphology of self-assembled nanoparticles are studied by TEM and DLS. |
