Description
上記したように、マイクロ流体デバイスにおいて流体を制御乃至管理する従来の方法は、マイクロメートルのスケールではない外部装置及びポンプ機構を使用する。これらのソリューションには、マイクロ流体システムの応用範囲を制限しうるいくつかの不都合がある。たとえば、マイクロ流体デバイス内に流体を注入して流体の流れを生成するために、外部の注射器及び空気ポンプが使用されることがある。しかしながら、外部の注射器及び空気ポンプは大きくて、取り扱うのも設定するのも難しく、接続の信頼性も低い。これらのタイプのポンプは、マイクロ流体デバイス/チップが適合することができる外部の流体接続の数によって、その多用性の点でも制限を受ける。
図1は、本開示の1実施形態にしたがう、(本明細書に開示されている)マイクロ流体デバイス、ネットワーク、及び慣性ポンプを組み込むのに適したマイクロ流体システム100を示す。マイクロ流体システム100を、たとえば、分析システム、マイクロエレクトロニクス冷却システム、ポリメラーゼ連鎖反応(PCR)システムなどの核酸増幅システム、または、同じ体積の流体の使用及び/または操作及び/または制御を伴う任意のシステムとすることができる。マイクロ流体システム100は、広範なマイクロ流体応用を可能にするために、典型的には、マイクロ流体チップ(たとえば「ラボオンチップ」)などのマイクロ流体デバイス102を実装している。マイクロ流体デバイス102は、一般的に、流体をネットワーク中を循環させるための慣性ポンプを具備するチャネルを有する1以上の流体ネットワーク103を備える。一般に、マイクロ流体デバイス102の構造及びコンポーネント(構成要素)を、電鋳法、レーザーアブレーション、異方性エッチング、スパッタリング、ドライエッチング、写真平板(フォトリソグラフィー)、キャスティング、成形(モールディング)、スタンピング、機械加工、スピンコーティング、積層法などの従来の集積回路微細加工技術を用いて製造することができる。マイクロ流体システム100は、流体をマイクロ流体デバイス102に供給し及び/または循環させるための外部の流体容器(たとえば液体タンク)104を含むこともできる。マイクロ流体システム100はまた、電子制御装置(電子コントローラ)106、並びに、マイクロ流体デバイス102、該電子制御装置106、及び、システム100の一部とすることができる他の電気的構成要素(電気コンポーネント)に電力を供給するための電源108を備える。
