Chemically labeled nucleotides and oligonucleotides encode DNA for sensing with nanopores.

Abstract excerpt

The labeling of nucleotides and oligonucleotides with reporter groups is an important tool in the sequence-specific sensing of DNA, as exemplified by fluorescence tags. Here we show that chemical tags can encode sequence information for electrical nanopore recordings. In nanopore recordings, individual DNA strands are electrophoretically driven through a nanoscale pore leading to detectable blockades of ionic...
