Loop-mediated isothermal amplification Thermostatic amplifying instrument is equipped with core digital microfluidic chips and adopts the isothermal amplification technology and the digital microfluidic technology, eliminating the temperature cycling, simplifying the template preprocessing, and achieving automatic nucleic acid extraction, purification, amplification and genotyping tests automatically. The product has the characteristics of fast reaction, high amplification efficiency, less sample consumption, etc., and can be widely used in the detection of infectious diseases caused by pathogenic microorganisms, the tumor liquid biopsy based on CTC capture or ctDNA and the tumor molecular classification. High speed By controlling the microdroplet reaction reagent, the reaction solution circulates between different temperature zones, and the whole speed of reaction and detection is increased.  High precision With millimeter level pixel design, the smallest microdroplet volume is as low as 1 microliter. Cost controllable The cost per chip (unit size) is only one tenth of other microfluidic devices produced by MEMS process. Wide range of application It drives liquid droplet by electric potential and interface surface force rather than external forces such as microfluidic pump, and can be widely used in molecular diagnosis, gene library construction, gene sequencing and many other fields. |
