摘要：

The induced circular dichroism of disperse red dye in the diblock copolymeric nanoparticles and phase transitions of the dye incorporated in thermosensitive poly(γ-benzyl L-glutamate) (PBLG)/poly(N-isopropylacrylamide) (PNIPAAm) nanoparticles with temperature changes were investigated. The amphiphilic diblock copolymers containing PBLG as a hydrophobic part and PEO or PNIPPAm as a hydrophilic part were self-assembled in aqueous media as the core-shell type nanoparticles.
