Description
ナノポアは、デオキシリボ核酸(DNA)及びリボ核酸(RNA)のシークエンシング(sequencing)といった応用向けに、広く使用されている。一例では、ナノポアシークエンシングは、電気的検出法を使用して実施され、この電気的検出法は、一般に、導電性流体に浸漬されているナノポアを通して未知の試料を搬送すること、及びナノポアの両端間に電位を印加することを含む。ナノポアを通るイオン伝導から生じる電流が測定される。ナノポア表面全体における電流密度の大きさは、ナノポア寸法、及び当該時点でナノポアを占有している試料(DNA又はRNAなど)の組成に依存する。種々のヌクレオチドは、ナノポア表面全体における電流密度に特徴的な変化を引き起こす。かかる電流変化は、測定され、DNA又はRNAの試料をシークエンシングするために使用される。
