Development of 'Eunnano Filter' for Infectious Disease Suppression Cooperation Facilities

[Asia Economy Reporter Junho Hwang] Domestic researchers have developed a filter material capable of filtering infectious disease bacteria or viruses within an air conditioning system that circulates indoor air.

The Korea Institute of Materials Science announced on the 24th that a research team consisting of Dr. Jihyun Kim, Dr. Changsoo Kim, and Dr. Seunghoon Lee from the Surface Technology Research Division succeeded in developing an antibacterial material capable of suppressing infectious diseases that can be transmitted through the air.

The research team developed a material that maximizes antibacterial power by treating silver nanowire material with an electron beam on filter materials used in various products. Silver nanowire material is used as a transparent electrode in next-generation flexible displays, touch panels, and other devices.

When an electron beam is irradiated onto the silver nanowire material, silver ions can be easily released. Additionally, as the surface area increases, it can effectively sterilize airborne bacteria such as those captured by the filter. The research team evaluated the antibacterial properties of this material against Escherichia coli and Staphylococcus aureus, and reported high antibacterial activity.

Dr. Changsoo Kim said, "We maximized antibacterial properties using nanomaterials in a simpler and more eco-friendly way than conventional methods, and we expect this to greatly contribute to the development of technologies that alleviate public concerns caused by bacteria or fine dust in the future."
