田和圭子・生命環境学部教授らが早稲田大学の井村考平教授のグループとともに取り組んだBull’s eye型プラズモニックチップにおけるナノアンテナ効果に関する論文が2月18日Optics expressに掲載されました。同心円構造のBull’s eye型プラズモニックチップ上に結合された蛍光性ナノ粒子からの蛍光は、中心でのみ輝点として観察されます。これは伝搬型プラズモンが中心に集まって蛍光を増強しますが、Bull’s eye型構造の違いによる増強度の違いを実験と計算から明らかにしました。

The research results of the groups of Prof. Keiko Tawa School of Biological and Environmental Science and of Prof. Kohei Imura Waseda University, who have been working to clarify the nanoantenna effect observed at the center of concentric circle in the Bull’s eye-type plasmonic chip, were published in Optics Express on February 18. The fluorescence from fluorescent nanoperticles adsorbed on the Bull's eye-type plasmonic chip was observed as bright spot in the center of a pattern. The structure dependence of the enhancement as nanoantenna effect was investigated by optical experiment and theoretical simulations.
