Research Abstract

Monodisperse polymer vesicles were obtained from head-tail type polycations composed of polyamidoamine (PAMAM) dendron and poly(L-lysine) tail (PAMAM dendron-PLL) in the mixing solvent ofmethanol and water. The introduction of cross-linkages between PLL tails using cross-linker bearing glycidyl groups at both ends provided the stabilization of vesicular structure of PAMAM dendron-PLL vesicles. Also, 4-carboxy-phenylboronic acid were introduced to the remained Lys residues using condensation reagent. For thus obtained nanocapsules with and without phenylboronic acid moieties, the change in average diameter with pH was evaluated by dynamic light scattering measurement. The prepared nanocapsules could show the size change through the change of ionization state of phenylboronic acid moieties, and this expected that the nanocpasules could exhibit the size change synchronizing with the change in glucose concentration.
