- UNIST development of ‘condensation -based virus collection+paper immune sensor’ based monitoring system
[서울경제]
Domestic researchers developed a technology that quickly found influenza viruses that wandered indoor air while the flu that stumbled in the school showed signs of re -trend. In schools and hospitals, viral infectious diseases such as the flu and corona will be detected early to help prevent spread.
According to the Ulsan Institute of Science and Technology (UNIST) on the 3rd, Professor Jang Jae -sung, a professor of mechanical engineering, developed a new surveillance system that can collect and analyze viruses in indoor air without damage. Unlike the virus capture method used in the existing epidemiological surveys, type A flu virus was detected by this system.
The system first inhales the air into the device, then condenses moisture in the virus particles, and detects it as a paper immune sensor. The virus in the air is small and light, so it is not well collected, so water droplets on the surface of the virus make it big and heavy. If you create a fast air flow inside, the virus water water is a principle that collides on the surface of the collector without following the air flow by inertia.
Move the virus samples gathered in the collector to a paper immunodefine sensor to find out the virus without the virus within 30 minutes. The immune sensor is a detection technology that uses antigen antibody reactions of protein. Hemaglutinine (ha) and nucleus protein (NP) on the surface of the virus are detected by reacting with the antibodies.
The developed system not only shortens the virus detection time, but also estimates whether the detected virus has a real infection. Existing PCR inspection requires a method of detecting the genetic material (DNA, RNA) of the virus, and it takes time to amplify the dielectric substance, which takes at least several hours. In addition, it is also detected that the genetic material of the dead virus is also detected. On the other hand, Hemaglutinine protein, which is detected by the technology developed by the professor’s research team, is characterized by the greater the contagious of the virus.
In fact, the research team collected and analyzed a total of 17 air samples from elementary school classrooms, corridors, and restaurants, and four of them were detected in the A -type flu virus (H1N1). Viruses were not detected as commercial equipment used in aerosol epidemiology. Professor Jang Jae -sung said, “The technology developed this time can be applied to various respiratory viruses, including Influenza, as well as Influenza 19.
The study was published on March 30 at the International Journal Environmental Science & Technology, published by the American Society of Chemicals (ACS). The research was carried out with the support of the Korea Research Foundation and the Ministry of Environment.

The flu, or influenza, is a contagious respiratory illness that can spread rapidly, especially in environments like classrooms and food planning areas. Early detection of the flu is crucial to prevent widespread outbreaks and minimize disruption to daily life. This involves not just recognizing symptoms but also leveraging advanced technology for floating virus measurement, enabling proactive interventions.
The Critical Importance of Early Flu detection
Why is early detection so vital? The answer lies in the flu’s rapid transmission rate. A single infected individual can quickly spread the virus, leading to absenteeism, reduced productivity, and potential health complications, especially for vulnerable populations like young children, the elderly, and those with underlying health conditions. In environments where many people are close together, like classrooms or busy food prep kitchens, the risk is amplified.
- Reduces Transmission: Identifying infected individuals early allows for prompt isolation and reduces the chances of the virus spreading to others.
- Protects Vulnerable Groups: Early detection safeguards vulnerable populations who are at higher risk of severe flu complications.
- Minimizes disruptions: By containing outbreaks early,schools and businesses can avoid widespread closures and disruptions to operations.
- Facilitates Timely Treatment: Early diagnosis enables prompt treatment with antiviral medications, which can shorten the duration and severity of the illness.
Current Methods of Flu Detection: Limitations and Challenges
Traditional methods of flu detection rely heavily on symptom recognition and laboratory testing. However,thes approaches have limitations. Individuals may not recognize early symptoms, or they may attribute them to a common cold. laboratory tests, while accurate, require time to process, delaying diagnosis and intervention.
- Symptom-Based Identification: Relies on subjective reporting and may not capture asymptomatic or pre-symptomatic individuals.
- Laboratory Testing: Requires sample collection and processing, which can take time and resources.
- Lack of Real-Time Monitoring: Current methods provide a snapshot in time rather than continuous monitoring of virus presence.
- Potential for Underreporting: People may not seek medical attention for mild symptoms, leading to an underestimation of the actual infection rate.
Introducing Advanced Floating Virus Measurement Technology
To overcome the limitations of traditional methods, researchers are developing innovative floating virus measurement technology. This technology allows for real-time monitoring of airborne viruses, providing an early warning system for potential outbreaks. This is especially crucial in environments like classrooms and food preparation areas.
