本明細書において使用される用語「アルキル」は、特に指定されない限り、炭素原子1〜10個を含有する直鎖または分岐鎖炭化水素を意味する。アルキルの代表的例には、メチル、エチル、n−プロピル、イソ−プロピル、n−ブチル、sec−ブチル、イソ−ブチル、tert−ブチル、n−ペンチル、イソペンチル、ネオペンチル、n−ヘキシル、3−メチルヘキシル、2,2−ジメチルペンチル、2,3−ジメチルペンチル、n−ヘプチル、n−オクチル、n−ノニルおよびn−デシルが含まれるが、これらに限定されない。「アルキル」基が2つの他の部分間の連結基である場合、やはり直鎖または分岐鎖とすることができる;例には、−CH2−、−CH2CH2−、−CH2CH2CHC(CH3)−、−CH2CH(CH2CH3)CH2−が含まれるが、これらに限定されない。
ステンレス鋼膜は、Hitachi Chemical Companyから入手できる。銅を電着して、金属層を付加し、銅層は、ジアゾニウム共役抗体を電解グラフトすることによって機能化される。改質前に、膜は、不動態ステンレス鋼表面を有する。抗体を共役した後、ターゲット分子例えばウイルスタンパク質の存在下で、膜の気孔を崩潰することができる。したがって、膜はウイルスを濾過除去するだけでなく、孔径を狭くし、それにより流速を低下させて、使用者にウイルスの存在を警告するであろう。したがって、ターゲット分子が存在しないと、高い流量(より低い濾過効率を伴う)を達成することができ、ターゲットが存在すると、より低い流速(制限された気孔により)を生じる。最終的に、ENSTRIP(登録商標)S−180で銅を剥離して、ステンレス鋼表面を再生させる。
