All-in-one molecular diagnosis cartridges and analysis equipment technology allowing for quick on-site diagnosis of infectious disease (swine flu, MERS, STD) by a semi-professional


Client / Market

  • In Vitro diagnostic, molecular diagnosis market


Necessity of this Technology

  • The occasions calling for quick diagnosis due to the emergence of new virus diseases are increasing, and the demand for the DNA test for disease prevention has increased.
  • The DNA test for detecting virus mostly uses the PCR method or isothermal amplification, so the test is conducted with an electrophoresis tool or a real-time PCR machine. However, out of the necessity at the field, a simpler, automated DNA test is demanded.
  • A lot of time is consumed for pre-treatment of a specimen, mixing of a specimen and a reagent, and the residue treatment. And the existing specimen pre-treatment device has a complex structure with high production cost and consumable expenses. While treating a large amount of specimens at once, the specimen could possibly be contaminated.


Technical Differentiation

  • It is mechanically simple and effectively handles the specimen pre-treatment.
  • It automatizes the entire process – nucleic acid extraction, amplification and detection
  • Nucleic acid extraction is easy. (30 minutes. 60 to 90 minutes for testing)
  • It includes the chambers that store reagents to be mixed with the specimen, and the reagents are connected to the specimen pre-treatment device, where specimens are discharged from each chamber in order according to the pre-treatment process order. This simplifies the pre-treatment device and integrates the nucleic acid amplification and detection device, which the nucleic acids extracted from the specimen flow in.

Excellence of Technology

  • Prototype process chart
  • Through the internal research project and the government-entrusted assignment, the prototype for the fully automatic nucleic acid extraction with the all-in-one cartridge and the single channel isothermal (61 degree) amplification and detection was produced and its performance was verified.
  • The basic system for multiplexing PCR through multichannel optical modules was completed.
