Claims (5)
- 生物学的、化学的及び医学的な分析のためのマイクロ流体工学チップであって、該マイクロ流体工学チップ内に複数のキャビテーション及びこれらのキャビテーションを互いに接続する、分析及び総合に必要な液体を毛管作用に基づいて搬送する複数の通路が配置されており、前記キャビテーションの内の少なくとも1つが反応室である形式のものにおいて、
3D層モデルに基づいた、光硬化性の親水性プラスチック材料から成る層状構成と、疎水性材料から成る被覆層とが設けられており、親水性材料から構成された層体内で、複数の異なるキャビテーション(1,2)から交差せずに延びる通路(6,8)が少なくとも1つの反応室(7)に開口していることを特徴とする、マイクロ流体工学チップ。 - チップに疎水性の層によって被覆された中央キャビテーション(1)が製作されており、この中央キャビテーションが環状に形成されたキャビテーション(2)によって包囲されており、この環状に形成されたキャビテーションが、やはり疎水性の層によって被覆された、ウェブ(5)によって互いに隔てられた複数の開口(4)を有しており、これらの開口から各1本の通路(8)が、各開口に対応配置された反応室(7)に通じており、この反応室が、他の反応室と共に前記の中央キャビテーション(1)及び環状キャビテーション(2)の周りに星形に配置されている一方で、中央キャビテーション(1)からウェブ(5)の表面に通じた、環状キャビテーション(2)を架橋する通路(6)がそれぞれ対応配置された反応室(7)に通じており、環状キャビテーション(2)及び中央キャビテーション(1)から出発する通路(6,8)が、それぞれ垂直方向で各キャビテーション(1,2)の壁に生じる、キャビテーション(1,2)の内室に向かって開いた溝に移行している、請求項1記載のマイクロ流体工学チップ。
- 垂直方向で壁に配置された通路(6,8)のキャビテーション底部側の端部が、底面と共に所定の鋭角を形成している、請求項2記載のマイクロ流体工学チップ。
- まず最初に光硬化性のプラスチック材料製の1つ又は複数の層から成る1枚のシートを製作し、最後の層を部分的にしか重合させず、このようにして得られたシートの部分重合された層を、予め製作されたマイクロ流体工学チップに載置し且つここまで部分的にしか重合させなかった層を完全に重合させ、これにより、チップに一体的な構造を与えることを特徴とする、請求項1から3までのいずれか1項記載のマイクロ流体工学チップ用の被覆層を製作するための方法。
- シートを少なくとも1対のローラ間で連続的に形成し、光硬化性材料を両ローラ間に配置し、これらのローラの内の一方に、硬化に使用される照射装置を設け、このようにして形成した被覆層をやはり連続的な方法で、大量生産されたマイクロ流体工学チップに載置して完全に重合させる、請求項4記載の方法。
