Current Progression: Application of High-Throughput Sequencing Technique in Space Microbiology

Figure 2

Nanopore DNA sequencing using electronic signals as detection methods. The diameter of the nanoscale is very small, and only a single DNA molecule is allowed to pass through. When a single strand of DNA passes through, it blocks the flow of ions and changes the current intensity across the nanopore. Because the charge properties of the four bases of ATCG are different, the type of base passed is identified according to the change property [25–28].
