Description
[001] 本出願は、「ゲート化電流測定器」と題した2005年7月20日付出願の米国仮出願番号60/700,787、および「バイオセンサ用の異常出力検出システム」と題した2006年5月8日付出願の米国仮出願番号60/746,771の利益を主張し、それらの全ての内容は本明細書中に参考文献として援用されている。
[002] 生物学的液体中の分析目的物の定量測定は、生理学的異常の診断および治療に有用である。例えば、血液などの生物学的液体中のグルコース濃度を決定することは、頻繁に血糖値をして、食事内容および/または薬物療法を制御しなければならない糖尿病患者個体にとって重要である。
[0026] サンプルに180秒以内に少なくとも3回の負荷サイクルを含むパルスシークエンスを印加することを含むサンプル中の分析目的物の濃度を決定する方法が提供される。負荷サイクルはそれぞれ、固定電位での励起および緩和を含んでもよく、励起のあいだには電流を記録することができる。パルスシークエンスは終端読み取りパルス(terminal read pulse)を含んでもよく、また作用電極上に拡散バリア層(diffusion barrier layer; DBL)を含んでいるセンサストリップに印加されてもよい。決定された分析目的物の濃度は、180秒以内に少なくとも3回の負荷サイクルを含んでいるパルスシークエンスを行わない同じ方法または異なる方法に比べ、メディエータバックグラウンドに起因しうるバイアスがより少ないと考えられる。一過性電流データの使用を通じて、定常状態条件がパルスシークエンスの負荷サイクルの励起部で達成しない場合に、分析目的物の濃度を決定することができる。データ処理は測定電流に適用され、サンプル中の分析目的物の濃度を決定することができる。
[0035] 「分析目的物」という用語は、サンプル中に存在する一種類または複数種類の物質として定義される。分析は、サンプル中に存在する分析目的物の存在および/または濃度を決定する。
[0042] 「測定装置」という用語は、センサストリップの伝導体に電位を印加し、そして生じた電流を測定しうる、一種類または複数種類の電気的装置として定義される。測定装置にはまた、記録された電流値に応じて、一種類または複数種類の分析目的物の存在および/または濃度を決定する処理能力を含まれていてもよい。
[0048] 「メディエータバックグラウンド」という用語は、内在の分析目的物の濃度に応答しない測定可能種に起因しうる、測定された分析目的物の濃度に導入されたバイアスとして定義される。
[0050] 「酸化還元対」という用語は、異なる酸化数を持つ化学物質の2つの共役種として定義される。より高い酸化数を持つ種の還元は、より低い酸化数を持つ種を生じる。逆に、より低い酸化数を持つ種の酸化は、より高い酸化数を持つ種を生じる。
[0060] 「平均初期厚」という用語は、液体サンプルを導入する前の層の平均厚についていう。平均という用語が用いられるのは、上部表面層が凸面と凹面を持ち、平坦ではないためである。
[0082] 本発明は、複数の負荷サイクルを含むゲート化電流測定パルスシークエンスが、分析完了時間を減少させながら、分析の正確性および精度の改善を提供することができる、という知見を使用する。各負荷サイクルには、比較的定電圧で提供することができる励起が含まれる。各負荷サイクルにはまた、開回路によって提供することができる緩和が含まれる。本発明のパルスシークエンスは、付加的な遅延およびパルス、例えば試薬の再水和を提供するための「インキュベーション」遅延、電極を回復するための「バーンオフ」パルス、ならびにメディエータの酸化状態を回復するためのメディエータ再生パルスなど、の必要性を除去することにより、分析に必要とされる時間を減少させることができる。
9×(0.5秒オン + 1.0秒オフ)+ 0.5秒 = 14秒、RI = 5/14 = 0.357.
パルスシークエンス(b)は:
9×(1.0秒オン+ 0.375秒オフ)+ 1.0秒 = 13.375秒、 RI = 10/13.375 = 0.748
である。
G8.5 = (i8.5 - Int8.5)/Slope8.5、G10= (i10 - Int10)/Slope10,、およびG11.5 = (i11.5 - Int11.5)/Slope11.5
となる。理論上、これら3つのグルコース値は同値であるはずであり、ランダムな変動によってのみ異なるはずである。したがって、グルコース値G8.5、G10およびG11.5は平均化されてもよく、また(G8.5+ G10 + G11.5)/3で最終的なグルコース値が計算されてもよい。検量線から値を平均化することで、1/√3の割合でノイズの減少をすることができる。
[00165] 図9Bは、充填量不足のセンサおよび正常に充填されたセンサ間での減衰特性、特に3から7秒の範囲で、実質的差異があることを立証する。充填量不足を、実際の減衰定数と以前に選択された値との間の差を比較することにより、減衰定数特性から決定することができる。例えば、図9Bに関して正常に充填されたセンサについては、上限として−0.1が選択される場合、3から5秒間での励起から決定された−0.1より低い値を有するK1定数は、正常に充填されたとして判断することができる。同様に、−0.1より高いK1値を有するセンサは、充填量不足と判断することができる。このように、充填量不足は、一過性電流特性から得られる減衰速度に応じて決定することができる。
