In this regard, it should be noted that the adapters used are different . DNA translocation through graphene nanopores. Answer: Fun question and it is of course not simple to answer. Bot. In May 2017, ONT released the 1D2 method together with the R9.5 nanopore; in this method, instead of being physically connected by a hairpin adapter, each strand is ligated separately to a special adapter (Fig. Pitt, M. E. et al. Huang, N. et al. Using nanopore sequencing, a single molecule of DNA or RNA can be sequenced without the need for PCR amplification or chemical labeling of the sample. Changes in the ionic current during translocation correspond to the nucleotide sequence present in the sensing region and are decoded using computational algorithms, allowing real-time sequencing of single molecules. Lv, X., Chen, Z., Lu, Y. 37, 783792 (2019). The membrane is resistant to the electric current, meaning the only way for current to flow across the membrane is to travel through the pore. Rep. 8, 14408 (2018). However, development of corresponding bioinformatics tools, especially for quantitative analyses, remains inadequate.
