Outline of Research at the Start

金ナノ粒子と放射線との併用ではサイズや表面修飾の重要性が判明し、放射線増感効果の検証とメカニズムの解明は急務である。そこで、金ナノ粒子のアクティブターゲッティングを利用した放射線癌細胞死の増強法を目指す。初めにサイズ、表面修飾の違いによる水溶液系での活性酸素種生成と細胞致死効果を調べる。次に細胞表面修飾の点から細胞死のメカニズムを検証する。また、分子レベルで相互作用と増強メカニズムの解明のため、超音波、大気圧プラズマや温熱との併用を目指すとともに、選択的な細胞死制御による放射線ナノメディシンの確立を目指す。

Outline of Final Research Achievements

For radio-sensitization using active targeting nanoparticles, liposomes with EGRF antibodies containing 5 nm gold nanoparticles were produced. When liposomes labeled with rhodamine containing FITC-gold nanoparticles were incubated in culture medium, both cellular incorporations were enhanced. On the other hand, almost no difference was found in tumors with intravenous injection or intratumor injection. Although there is a possibility of radio-sensitization using active targeting nanoparticles, drug delivery to intratumor tissues is still a major problem.
