摘要

We explored the use of polymer tags and nanopore for single-molecule electronic detection of nucleic acids and proteins. In this paper, we first report our progress of the research and development of a single molecule real time nanopore-based DNA sequencing by synthesis strategy that accurately distinguishes the 4 bases (A, C, G, T) by electronically detecting 4 different polymer tags attached to the 5'-phosphate-modified nucleotides during polymerase reaction. Then, we present the development of a strategy for an electronic multiplex single nucleotide polymorphism assay using a library of oligonucleotide primers labeled with polymer tags of different lengths by nanopore detection with single molecule sensitivity. The single molecule electronic detection and analyses of target nucleic acids with polymer tagged oligonucleotides are also described. Finally, an approach for the single molecule electronic detection of protein-protein interactions using nanopore and polymer tags is presented.
