AI Technical Summary

Technical Problem

Existing nucleic acid extraction methods are cumbersome and cannot meet the rapid testing needs of emergency situations, and the magnetic bead method has low detection sensitivity in large-volume samples.

Method used

Nucleic acid is adsorbed by cationic magnetic beads through electrostatic binding and extracted using lysis preservation solution, simplifying the operation process and enabling direct PCR detection.

Benefits of technology

It enables rapid and simple nucleic acid extraction and enrichment, improves detection sensitivity, and is particularly suitable for emergency testing.
