Abstract
Description
本特許は、プラズモンを生成する原理およびプラズモンナノ粒子表面の改質に基づく携帯型ナノ光学チップの構造に関する。ナノ光学チップは、環境(水、空気、土壌)、食品、生体系中の非常に低い濃度の物質/分子を検出する。
プラズモンは、金属ナノ粒子上の光によって励起される電子プラズマの振動であり、励起は、ナノ粒子の表面上に有意に増強された電磁場(EF)を生成する。SERS(表面増強ラマン分光法)は、金属ナノ構造上のEFの顕著な増強と、それに続くラマンシグナルの強度の増加に基づく技術である。このような増加したラマンシグナルは、構造分析法から、非常に低い分子濃度を単一分子レベルまで検出することができる構造的に感度の高いナノプローブへラマン分光法を変換する。
ナノ光学チップは、基板上に堆積されたプラズモンナノ粒子からなるプラズモンナノ粒子表面と、プラズモンナノ粒子表面の分子官能化という2つの異なる部分を統合する。
ナノ光学チップは、環境(水、空気、土壌)、食品、生体系中の物質/分子を検出することができる。認証技術(質量分析法またはガスクロマトグラフィー)によるこれらの物質/分子の検出および同定は、時間がかかり、高価である。認証方法(質量分析法またはガスクロマトグラフィー)と比較して、ナノ光学チップによる物質/分子の検出は、より安価で、より高速で、より高感度で、スポット上で実施される(実験室でのサンプルの前処理を必要としない)。
EF 電磁場
SERS 表面増強ラマン分光法
HS ホットスポット(EFの高輝度領域)
PLD パルスレーザー蒸着
NP プラズモンナノ粒子
BL 二官能性リンカー
CL キャビタンドリンカー

- 一次プラズモンナノ粒子表面2が、一次プラズモンナノ粒子表面上で選択された分子の結合および検出のための好ましい条件を作り出す特定のCL、BLリンカーおよび/または他の分子によって官能化される3ことを特徴によって特徴付けられる、請求項1に記載の環境、食品、および生体系中の物質/分子を検出するためのナノ光学チップの構造。
