Description
本発明は、大まかに言って、分析装置に関し、より詳しく言うと、ミクロな流体の分析システムの製造に用いる材料に関する。
流体サンプルに基づく分析装置(すなわち、流体の分析装置)では、必要な流体サンプルが、信頼できる分析結果を得るために、高い程度の正確度(accuracy)および精密度(precision)で制御されなければならない。そのような制御は、例えば10nl(ナノリットル)から100μl(マイクロリットル)までの少ない体積の流体サンプルを用いる「ミクロな流体の(microfluidic)」分析装置に関しては特に保証されている。そのようなミクロな流体の分析装置では、流体サンプルは、典型的には、例えば10μmから500μm程度の寸法のマイクロチャネル(microchannel)に収容されマイクロチャネル内で移送される。
本発明の実施の形態に基づく融合可能な導電性インクは、ミクロな流体のシステム内での電極への頑健かつ強固な電気的な接続が提供されるように、ミクロな流体のシステムを製造するのに用いることができる。さらに、融合可能な導電性インクは、ミクロな流体のシステム内のマイクロチャネルが液密および/または気密になるようにするためにも用いることができる。
本明細書を通して一貫性を保つため、および、本発明を明瞭に理解するために、以下の定義が本明細書で用いられる用語について行われる。
(1)ラミネート層の底面の少なくとも一部が、絶縁基板の上面の少なくとも一部と接着され、
(2)電極が少なくとも一つのマイクロチャネルに露出され、
(3)導電性トレースの各々が、少なくとも一つの導電性接触パッドと電気的に接触し、
(4)導電性接触パッドの少なくとも一つの表面が、露出されていて電気的に接続するためにアクセス可能な状態に留まる、
ように、絶縁基板に接着される。図9Bは、ステップ830の結果の構造を示している。
本発明に基づくミクロな流体の分析装置のある実施の形態が、ポリスチレン材料(すなわち、ドイツ国ルードビッヒシャフェン(Ludwigshafen)D−67056のビー・エー・エス・エフ・アクティエンゲゼルシャフト・ビジネス・ユニット・ポリスチレン(BASF Aktiengesellschaft, Business Unit Polystyrene)から市販されているポリスチロール144C(Polystyrol 144C))で形成された絶縁基板と、別のポリスチレン材料(すなわち、ドイツ国ノーデンハム(Nordenham)26954、ノードドイッチェ・ゼーカベルベルケ(Norddeutsche Seekabelwerke)のエヌ・エス・ダブリュー・クンスツストッフテヒニーク(NSW Kunststofftechnik)から市販されているノーフレックス・フィルム(Norflex(登録商標) Film))で形成されたラミネート層とを用いて、製造された。
重量比が1:9の白金および炭素を含有する超微粉末(例えば、イギリス国SG8 6NT、サウス・ケンブリッジシェア(South Cambridgeshire)、メルドレス(Meldreth)、ノース・エンド(North End)、ユニット1Aロング・バーン(Unit 1A Long Barn)のエム・シー・エー・サービシス(MCA Services)から入手可能なMCA 20V 白金炭素(platinized carbon))を18.5%、
ポリビスフェノールA−コ−エピクロロヒドリン−グリシジル・エンドキャップポリマー(poly(bisphenol A-co-epichlorohydrin)-glycidyl end capped polymer:例えば、オランダ国3190ANホーフリート・ライト(Hoogvliet Rt)ピーオーボックス606のレゾリューション・ユアロップ・ビー・ブイ(Resolution Europe BV)、レゾリューション・エンハンスト・プロダクツ(Resolution Enhanced Products)から入手可能なエピコート1055(Epikote(商標)1055))を19.0%、および、
メチルカルビトール(ジエチレングリコールモノメチルエーテル)溶剤(ベルギー国2650エデゲム(Edegem)、プリンスボーデビィンラーン(Prins Boudewijnlaan)41のダウ・ベネルクス・ビー・ブイ(Dow Benelux B. V.)から入手された。)を62.5%
