Research Abstract

本研究では、温度応答型高分子であるポリN-イソプロピルアクリルアミド[poly(IPAAm)]をフェリチンの外殻に化学修飾し、それらの温度変化に伴う表面上への吸着挙動を観察し、グラフト鎖の影響について考察した。poly(IPAAm)修飾フェリチンを、種々の温度での疎水基板上への吸着挙動を観察した。それらの結果、低温の条件では、poly(IPAAm)修飾フェリチンは基板上には全く吸着しなかったのに対し、高温では基板上に吸着した。このことは、高温においてpoly(IPAAm)修飾フェリチンの疎水性度が上昇し、疎水基板との相互作用が上昇したことによる吸着を示唆している。
