Qpre (Quick Pre-detector) is a system that developed improved detection capability compared to existing field diagnosis devices by using the electrochemical detection source technology for three kinds of viruses (Noro, Rota, Adeno).
As existing on-site diagnostic devices are developed with the focus on ease of use, performance is not comparable to facilities such as diagnostic centers and hospitals. In order to solve the problems raised above, the innovative platform is equipped with ultra-sensitive sensing capabilities and portability that can diagnose even a small amount of viruses.
Major food poisoning viruses such as Noro, Rota, and Adeno are mainly found in samples such as feces and blood after human infection. It proliferates in a host such as a human cell, and is tested when clinical symptoms appear. In this case, diagnosis is possible because the amount of virus is sufficiently high. On the other hand, since the amount of virus is absolutely small before human infection, there is no technology for virus diagnosis other than PCR (polymerase chain reaction), which is a gene amplification technology. Such genetic diagnosis can be performed in a well-equipped diagnostic center, so a sample delivery process from the field to the diagnostic center is required. In addition, it is not possible to quickly determine the presence or absence of a virus from a sample because it takes from half a day to more than one day to obtain a diagnosis result. Infectious diseases can be prevented from spreading through early or prior diagnosis. Accordingly, rapid diagnosis of viruses in the field is required, and the development of an innovative platform that can perform these tasks has been developed.
