The MinION is a portable DNA sequencer developed by Oxford Nanopore Technologies. It allows researchers to analyze genetic material in real-time, making it useful for various applications, including genomics, environmental monitoring, and medical diagnostics. The device is small enough to fit in a pocket, enabling fieldwork and on-site testing. Using a technology called nanopore sequencing, the MinION reads DNA strands as they pass through tiny pores. This method provides long reads of genetic sequences, which can help identify variations and mutations. Its accessibility and ease of use have made it popular among scientists and researchers worldwide.
