但是如果用纳米孔，实质上就不需要化学与处理和“放大”，取而代之的是，可以一次一个碱基对地读出单条dna链，也不用标记。

With nanopores, however, virtually no chemical pre-processing is required and no amplification. Instead a single strand of DNA can be read, one base pair at a time, and without the need for labelling.

这个想法是单个的碱基对(DNA密码的四个化学字母)在他们通过纳米孔的时候，能流利地被一个一个读出(那四个字母是指a、T、C、G，译者注)。

The idea is that individual base pairs (the four chemical "letters" of the DNA alphabet) can then be read off one at a time as they pass through the nanopore.
