This technology was developed as a simpler and more easily scalable method of capturing higher-order chromatin structure and mapping regions of chromatin contact. In addition, Pore-C can be used to visualize epigenomic interactions due to the capability of ONT long-read sequencing to detect DNA methylation .
A quarter of the world's SARS-CoV-2 viral genomes were sequenced with nanopore devices. The technology offers an important tool for combating antimicrobial resistance. [11] In 2020, China-based Qitan Technology launched its nanopore single-molecule gene sequencer, [12] while in 2024 MGI Tech launched its own products. [13]
A nanopore is a pore of nanometer size. It may, for example, be created by a pore-forming protein or as a hole in synthetic materials such as silicon or graphene. When a nanopore is present in an electrically insulating membrane, it can be used as a single-molecule detector.
Sequencing technologies with a different approach than second-generation platforms were first described as "third-generation" in 2008–2009. [4]There are several companies currently at the heart of third generation sequencing technology development, namely, Pacific Biosciences, Oxford Nanopore Technology, Quantapore (CA-USA), and Stratos (WA-USA).
Oxford Nanopore Technologies plc is a UK-based company which develops and sells nanopore sequencing products (including the portable DNA sequencer, MinION) for the direct, electronic analysis of single molecules. [2] [3] [4] It is listed on the London Stock Exchange and is a constituent of the FTSE 250 Index. [5]
Other technologies have emerged, including Nanopore technology. Though the sequencing accuracy of Nanopore technology is lower than those above, its read length is on average much longer. [ 35 ] This generation of long reads is valuable especially in de novo whole-genome sequencing applications.
NanoString's research tools are based on the nCounter Analysis System, which is a modification of the DNA microarray technology. [11] The nCounter system allows for the simultaneous profiling of hundreds of genes, proteins, miRNAs, or copy number variations with high sensitivity and precision, using molecular barcodes and microscopic imaging in a hybridization reaction.
A nanopore battery is a rechargeable battery that is a composite of billions of nanoscale batteries formed within the pores of a substrate. [1] The space inside the holes is so small that billions of pores combined equal the volume of a grain of sand. Each pore's diameter was some one eighty-thousandth the width of a human hair. [1]
