Abstract
Description
本発明にかかる、がんセンサアレーについて、図5(a)を用いて説明する。まず、図5(a)に例示する、トラック状の流路を有する表面構造をもつSi半導体基板を、標準CMOSプロセスにより製作した。ここで、荷降ろし領域20と参照領域25の流路幅は1.2μm、荷積み領域90の円弧の流路幅は10μmとした。荷降ろし領域20と参照領域25の流路には、メタル配線層を利用した対向電極及び電極パッド91を形成した。
得られたSi半導体基板を、イソプロピルアルコールで1時間超音波洗浄し、無塵中で、60℃2時間加熱し、乾燥させた。さらに、表面コート剤(信越化学工業製、KJC7022)を0.001mg/mLに調整し、Si半導体基板にスピンコーターでコーティングした。これを無塵中で、60℃5時間加熱して乾燥させ、Si半導体基板の表面の疎水化処理を行った。
荷降ろし領域20と参照領域25を覆うカバーガラスを、洗浄液(0.1M KOH+70%エタノール)で1時間超音波洗浄後、さらに純水で洗浄した。無塵中で、60℃5時間加熱して乾燥させ、カバーガラスの表面を親水化した。
26μg/mLの骨格筋ミオシンを、25mM KCl、3.0mM MgCl2、5.0mM pH緩衝液(Tris-HCl)で希釈して得たpH=8.0のモーター蛋白溶液に、カバー蛋白質20μg/mLを加えた溶液を作製し、インクジェット方式でSi半導体基板のトラック全面に印刷した。
初期肺がんの腫瘍マーカーである、抗ヒトCEAモノクローナル抗体(1.0mg/mL)を抗体80として選択し、荷降ろし領域20にインクジェット方式で印刷した。
Sephadex G-25を用い、1.0mg/mLの抗ヒトCEAモノクローナル抗体0.5mLを、50mMリン酸緩衝液にて調整した。これに2000倍量の架橋剤であるSM(PEG)12(THERMO SCIENTIFIC社製)を加え、25℃で3時間反応させた。さらに、SM(PEG)12の50倍量のTris-HClを加えた後、50mMリン酸緩衝液にて調整した。これに、骨格筋アクチン繊維溶液(1.0mg/mLの骨格筋アクチン繊維を、25mM KCl、2.0mM ATP、0.1mM CaCl2、10mMクレアチンリン酸ナトリウム、10mg/mLクレアチンキナーゼにて希釈)を0.5mL加え、25℃で3時間処理後、SM(PEG)12の50倍量の2-メルカプトエタノールを加え、輸送ユニット蛋白を調整した。
輸送ユニット蛋白と、骨格筋アクチン繊維を1:10000の割合で、溶媒(25mM KCl、25mM imidazole-HCl(pH=7.4)、2.0mM MgCl2、10mM ATP、1mM DTT、10mMクレアチンリン酸、100U/mLクレアチンキナーゼ)中にて混合し、担体分子50となるナノ輸送繊維を得た。これを、Si半導体基板上に15μL滴下した。さらに、2.0μLを滴下し、表面の溶液2.0μLを吸引洗浄した。Si半導体基板上に、ジエチルアミノエチル(DEAE)イオン交換膜を装着、周囲の水分を吸引した。表面処理を行ったカバーガラスを装着し、親水性接着剤を用い、加圧して接着した。
がんセンサアレーに、腫瘍マーカーCEAを0.10ng/mLから100ng/mL含む人工血清を2.0μL滴下した。センサユニットの半導体回路を使い、インピーダンス計測を行った。測定は並列四端子法で行われ、流路の下に設けられた分析回路47で、荷降ろし領域20と参照領域25のインピーダンス変化を差動検出し、その出力値を電圧に変換した。また比較例として、化学発光免疫測定法を使い腫瘍マーカーCEAを検出した。両者の結果を図6に示す。この結果から、本発明による初期ガン検出能力は従来法と同等であり、電気的に測定できるため、安価で高速に行えることが判明した。
