Sequencing platforms are instrumental tools in modern molecular biology, enabling the determination of the order of nucleotides within a DNA or RNA molecule. These platforms have revolutionized fields ranging from genomics and transcriptomics to epigenetics and metagenomics. Early sequencing methods, such as the Sanger sequencing method developed in the 1970s, laid the groundwork for subsequent technological advancements. However, these initial techniques were labor-intensive and had limited throughput.

The advent of next-generation sequencing (NGS) technologies marked a significant leap forward. NGS platforms employ various biochemical and optical detection methods to sequence millions or even billions of DNA fragments in parallel. This massive parallelization dramatically increased the speed and reduced the cost of sequencing, making it accessible for a wide range of applications. Common NGS platforms include those based on sequencing-by-synthesis, sequencing-by-ligation, and nanopore-based technologies.

Each sequencing platform has its strengths and weaknesses in terms of read length, accuracy, throughput, and cost. For instance, some platforms excel at generating very long reads, which are advantageous for assembling complex genomes and identifying structural variations. Others produce shorter reads but offer higher accuracy and lower per-base costs, making them suitable for applications like exome sequencing and variant calling. The choice of sequencing platform often depends on the specific research question, experimental design, and available resources. Continuous innovation in sequencing technology promises further improvements in speed, accuracy, and affordability, further expanding the capabilities of biological research.
