Oxford Nanopore Technologies (ONT) is a company specializing in the development and commercialization of nanopore-based sequencing technologies. Their goal is to provide real-time, scalable, and accessible sequencing solutions that can be used in various fields such as healthcare, environmental monitoring, and research.
The core technology of ONT revolves around
nanopores, which are tiny holes, typically at the nanometer scale, embedded in a thin membrane. When a voltage is applied across this membrane, ions flow through the nanopore, creating an ionic current. As molecules such as DNA or RNA pass through the nanopore, they disrupt this current in characteristic ways, allowing the system to identify and sequence the molecules.
