Ion semiconductor sequencing

Ion semiconductor sequencing is a next-generation sequencing (NGS) technology that allows for the rapid and cost-effective processing of DNA sequences. Developed by Ion Torrent, this method differs from traditional sequencing techniques, such as those based on optical detection, by using a semiconductor chip to directly measure the release of hydrogen ions that occur during DNA polymerization. Here's a breakdown of how Ion semiconductor sequencing works: 1. **Library Preparation**: DNA samples are fragmented and adapters are ligated to the ends of the fragments.
