This innovative technology allows for real-time sequencing, offering advantages and disadvantages compared to other leading methods.

Nanopore sequencing leverages the principle of measuring changes in ionic current as a biological polymer (DNA or RNA) translocates through a nanopore. A nanopore, essentially a tiny hole, is embedded in a membrane separating two electrolyte solutions. As a nucleic acid molecule passes through this nanopore, it alters the flow of ions, producing a characteristic electrical signal. This signal is then decoded by sophisticated algorithms to determine the sequence of nucleotides (A, T, C, and G). The unique electrical signature of each nucleotide allows for its identification, thus revealing the genetic sequence.
