The applications are also organized by the corresponding strengths of ONT sequencing as three layers of the pie chart: (1) long read length, (2) native single molecule and (3) portable, affordable and real time. The advantages and disadvantages of short- and long-read sequencing are summarized in Table 1. . Weng, Z. et al.

Koren, S. et al. In forensic research, a portable strategy known as MinION sketching was developed to identify human DNA with only 3min of sequencing232, offering a rapid solution to cell authentication or contamination identification during cell or tissue culture. The detection of analytes and the sequencing of DNA using biological nanopores have seen major advances over recent years. As early as 2013, independent reports demonstrated that methylated cytosines (5mC and 5hmC) in DNA could be distinguished from native cytosine by the characteristic current signals measured using the MspA nanopore172,173. Analogous to next generation sequencing, the cost of sequencing using long-read technologies has materially dropped whilst the instrument throughput continues . Nanopore sequencing is the fourth-generation DNA sequencing technology and the significant advantages of nanopores (biological or solid state) include label-free, ultralong reads (10 4 -10 6 bases), high throughput, and low material requirement (Feng et al., 2015).

Direct RNA nanopore sequencing of full-length coronavirus genomes provides novel insights into structural variants and enables modification analysis. In addition to official ONT tools (for example, ont_fast5_api software for format conversion between single-fast5 and multi-fast5 and data compression/decompression), several third-party software packages40,58,59,60,61,62 have been developed for quality control, format conversion (for example, NanoR63 for generating fastq files from fast5 files containing sequence information), data exploration and visualization of the raw ONT data (for example, Poretools64, NanoPack65 and PyPore66) and for after base-calling data analyses (for example, AlignQC42 and BulkVis49) (Fig. Genomic detection of a virus lineage replacement event of dengue virus serotype 2 in Brazil, 2019. 1.

Methods 17, 319327 (2020). Cell 77, 985998 (2020). Philpott, M. et al. In both cases, only the RNA strand passes through the nanopore, and therefore direct sequencing of RNA molecules does not generate a consensus sequence (for example, 2D or 1D2). DiMeLo-seq: a long-read, single-molecule method for mapping proteinDNA interactions genome-wide. Recently, ONT was applied to characterize the methylomes from different biological samples, such as 6mA in a microbial reference community174 as well as 5mC and 6mA in E. coli, Chlamydomonas reinhardtii and human genomes76.

For instance, biological pores offer atomically precise structure . Unlike the 2D library, the complement strand in the 1D2 library is not guaranteed to follow the template, resulting in imperfect consensus sequence generation. The R10 and R10.3 nanopores with two sensing regions may result in different signal features compared to previous raw current data, which will likely drive another wave of method development to improve data accuracy and base modification detection. Moreover, ONT enabled the first gapless telomere-to-telomere assembly of the human X chromosome, including reconstruction of a ~2.8Mb centromeric satellite DNA array and closing of all remaining 29 gaps (totaling 1.1Mb)134.

Advantages of High-Throughput Sequencing: Process more samples to improve statistical power, and cost-effectively run emerging data-rich methods, including single-cell and spatial analyses. Ionic current passes through the nanopore because a constant voltage is applied across the membrane, where the trans side is positively charged. 10, 4660 (2019). Several tools have also been developed to investigate highly repetitive genomic regions by ONT sequencing, such as TLDR for identifying non-reference transposable elements118 and TRiCoLOR for characterizing tandem repeats119 (Table 1).
