'Sepsis Early Diagnosis Sensor Material' 2019 Outstanding Performance of Public Research Institutes

[Asia Economy Reporter Junho Hwang] The research team led by Dr. Sungkyu Park of the Nano Surface Research Laboratory, Surface Technology Research Division at the Korea Institute of Materials Science was selected on the 11th as one of the '2019 Outstanding Research Achievements of Government-Funded Research Institutes.'

The team developed a nanobiosensor material technology for ultra-sensitive early diagnosis of sepsis. They maximized the difference in surface energy between the substrate surface and the noble metal (gold, silver, copper, etc.) deposition materials and applied vacuum processes to develop a spherical noble metal nanoparticle deposition technology. Subsequently, they developed a sepsis diagnostic biosensor chip that overcomes the sensitivity limitations of existing biosensors by using an ultra-sensitive three-dimensional nanoplasmonic molecular sensing material.

This technology is significant in that it secured a production technology for large-area nanobiosensor substrates that are low-cost and easy to mass-produce. It is also meaningful because it enables early diagnosis and treatment of intractable diseases and infectious diseases including sepsis, as well as on-site detection of illegal drugs and harmful substances in food.

Dr. Sungkyu Park, the principal researcher, stated, "By implementing rapid diagnostic technology for sepsis through nanobiosensor material convergence technology, the mortality rate (about 20%) and medical costs can be drastically reduced." He added, "It can be utilized as a high-sensitivity sensor chip for diagnosing various infectious diseases including sepsis and avian influenza, as well as for healthcare point-of-care diagnostic devices, which will enhance the technological competitiveness of domestic in vitro diagnostic companies and support their entry into the global market."

Meanwhile, the National Research Council of Science & Technology annually announces outstanding achievements to foster pride among scientists and encourage research outcomes by discovering excellent research results from government-funded research institutes.
