Description
図5に示す分析装置31は、分析用チップ1の金属層5が設けられた面に対して測定光Iを入射させる光源である入射光ファイバ32と分析用チップ1から反射した反射光Rを検出する検出器である反射光検出ファイバ33とを備えた光源プローブ34と、タングステンハロゲン光源35と、検出器33で検出された光を分光する分光光度計36と、分光光度計36で得られた結果を処理するコンピュータ37とを備えている。光学プローブ34においては、検出器33を取り巻くように複数の光源32が配置され、検出器33と光源32とが一体化されている。
先ず、1cm四方のアルミニウム基材を用意し、480℃で40分間アニーリングした。次に、ダイヤモンド懸濁液を用いた機械研磨、その後、電解研磨を行うことにより基材表面の酸化膜を除去した。電解研磨は70℃で10分間、電流1.3Aとした。電解研磨で用いた酸性溶液はH3PO4とH2SO4とH2Oとを8.5:1:0.5の割合で混合し、35g/LのCrO3を含んでいる。
次に、以上のように作製した分析用チップを図5に示すような分析装置に用い、グルコース溶液の分析を行った。分析用チップにおける多孔質層の膜厚は3μmであった。
本実験においては、本発明の分析用チップを用いて試料中のプローブDNAの検出を試みた。先ず、実験に先立ち、多孔質層の膜厚と吸光度変化との関係について調べた。
