3.3.2020 15:02:26 CET | Business Wire | Press release
Seoul Viosys , a leading global provider of UV LED technology and a subsidiary of Seoul Semiconductor, announced that customer inquiries for its violeds UV LED products, which are ideal for sterilizing bacteria, increased more than five times over the previous month, fueled by concerns over the continuing global spread of the coronavirus (COVID-19).

According to the Ultraviolet Germicidal Irradiation Handbook1 , one minute of UV-C light will sterilize more than 90% of the coronavirus. In addition, tests conducted by Chinese agencies on air appliances equipped with the violeds UV LED sterilization technology have demonstrated a 97% reduction in airborne virus particles.
With the growing concerns over the global spread of the coronavirus, numerous automotive companies in China are actively reviewing adoption of Seoul’s violeds UV LED technology in sterilization systems for vehicle interiors. In addition, violeds UV LED technology has been used by the US National Aeronautics and Space Administration (NASA) aboard the International Space Station (ISS) to provide a healthy, germ-free environment for astronauts.
Seoul’s violeds UV LED technology has been adopted by Maltani, the largest Korean lighting company, for sterilization lighting applications, and by RGF Environmental Group, the No.1 in-duct air treatment supplier in the U.S., for its [Halo-LED™] indoor air quality system launched in November of 2019, as shown in this YouTube video . In addition, violeds UV LEDs are used in water purifiers from SK Magic Co., Ltd. and Hyundai Rental Care Co., Ltd.
Until recently, many companies have been conservative in their adoption of UV LED technology because conventional UV LEDs typically had a short lifetime (10,000 hours) and high cost. However, Seoul Viosys recently improved the lifetime of their violeds UV LED to more than 50,000 hours, similar to visible LEDs used for general lighting applications, and increased production capacity to achieve cost competitiveness.
“Seoul Viosys is committed to developing technology that protects human health and creates a cleaner world, and we have long been involved in developing UV LEDs for innovative biomedical and agricultural applications,” said CEO Chung Hoon Lee, CEO of Seoul Semiconductor, which established Seoul Viosys 18 years ago to develop UV-LED technology in strategic partnerships with Japanese and U.S. companies. “Through innovation, sustained research and development, and manufacturing experience, we were able to improve the lifetime of UV LEDs up to 50,000 hours and significantly reduce product cost. We hope that Seoul’s violeds UV LED technology will help protect human health and create a cleaner world in the face of the current health situation.”
Seoul Viosys is currently run by its CEO Young joo Lee, who started the company in 2002.

JEOL: Sales Launch of the Laser SEM System “LazEdge”25.5.2026 10:16:00 CEST | Press release
JEOL Ltd. (President & CEO: Izumi Oi) has developed the “LazEdge”, an SEM system equipped with a laser processing system, and begins sales on May 25, 2026. Cross-section preparation instruments such as the focused ion beam system (FIB system), are widely used in science and technology fields across research institutes, universities, and industries. In recent years, demand is increasing for a system that can process large-areas at a high speed, while achieving high-quality of the processed surface. “LazEdge” is an instrument integrating JEOL’s SEM with the laser technology proprietary of Hamamatsu Photonics K.K., and enables laser processing inside the specimen chamber of the electron microscope. This system enables high-quality cross-section specimens produced through high-speed, large-area processing to be transferred seamlessly to subsequent analyses, such as SEM observation, elemental analysis, and crystal orientation analysis, without exposure to the external environment. As a resu
TFG-001, A Novel 3D Neural Microtissue Cell Therapy, Demonstrates Superior Functionality and Reinnervation for Parkinson’s Disease25.5.2026 08:00:00 CEST | Press release
TreeFrog Therapeutics, a regenerative medicine biotech company developing next-generation cell therapies, today announced that it will present new preclinical data on TFG-001 at the 7th World Parkinson’s Conference. TFG-001, a 3D neural microtissue cell therapy, demonstrated rapid dopamine release and extensive graft-derived reinnervation across multiple advanced translational Parkinson’s disease models—supporting its potential as a best-in-class candidate. The critical need for reinnervation in Parkinson's disease In Parkinson's disease, an estimated 60–80% of dopaminergic neurons are already lost before motor symptoms even appear. The nigrostriatal pathway degenerates, destroying the essential wiring that connects dopamine-producing neurons to movement control. While chemical dopamine replacements (like levodopa) can manage symptoms, they cannot restore the spatial precision, feedback loops, or dynamic regulation of a healthy brain network. To achieve true functional restoration, it
