Nanopore sequencing technology has advanced significantly, offering long-read sequencing with high accuracy and throughput. This technology uses a nanoscale protein pore to detect ionic current changes as DNA or RNA molecules pass through, enabling real-time sequencing. The technology has been refined over time, with improvements in nanopore design, motor proteins, and base-calling algorithms. ONT's MinION device, introduced in 2014, has been pivotal in advancing nanopore sequencing, with subsequent versions like R9 and R10 enhancing accuracy and read length. The technology is applied in genome assembly, transcriptome analysis, and clinical diagnostics, with ongoing efforts to improve data quality and analytical methods. Nanopore sequencing can directly sequence RNA and detect modifications, offering advantages over traditional methods. It is also used for de novo genome assembly, identifying structural variations, and characterizing epigenetic marks. The technology's portability and real-time capabilities make it suitable for field applications, including rapid pathogen detection and outbreak surveillance. Despite challenges in accuracy and data processing, nanopore sequencing continues to evolve, with new tools and methods improving its utility in both basic and applied research. The integration of long and short reads in hybrid sequencing approaches enhances the resolution and accuracy of genomic and transcriptomic analyses. Overall, nanopore sequencing is a transformative technology with broad applications in genomics, transcriptomics, and clinical diagnostics.Nanopore sequencing technology has advanced significantly, offering long-read sequencing with high accuracy and throughput.
