Description
以上のように、さらなる微細化と高集積化の必要なDNAシーケンサでは、低コストの基板材料を採用しても、あるいは、光学的計測、電気的計測のどちらを採用しても、いずれにせよ、リソグラフィ、ドライエッチング微細加工などの半導体プロセスを用いて全ての高集積アレイ基板を製造している限り、製造コスト低減には限界がある。全ての基板の製造に半導体プロセスを適用しなくても量産できる製造技術の確立が望まれる。
実施例1として、樹脂基板を用いて、官能基スポットアレイ又はオリゴDNAスポットアレイを形成したスポットアレイ基板の製造例を説明する。
実用上好ましくはビーズ充填率が高く、少なくとも90%以上の有効なアレイスポットを形成することが望まれる。そこで、実施例2として、樹脂基板を用いて官能基スポットアレイやオリゴDNAスポットアレイなどの表面修飾スポットアレイを形成したチップを製造し、そのとき特に、ビーズ充填率を向上し、かつ分析中に脱落しない施策を施した例を示す。
次に、実施例3として、樹脂基板を用いて、官能基スポットアレイ又はオリゴDNAスポットアレイを形成したチップを製造し、そのとき特に、ビーズ充填率を上げかつ分析中に脱落しない別の施策として、ビーズの固定箇所での化学結合の効果並びにビーズ粒径分布の狭小化の効果を検討した。
実施例4として、スポットアレイ基板を組み込んだフローセルを用いた分析の例を示す。
実施例5として、スポットアレイ基板を組み込んだフローセルを用いた分析の他の例を示す。
