Mission/Background :
SEGNOS Co., Ltd. is a biotechnology startup developing innovative separation and diagnostic technologies based on proprietary stimuli-responsive magnetic nanoparticles. Founded through the fusion of corporate carve-out innovations and university-originated technologies, the company aims to become a global niche leader in magnetic nanoparticle-based diagnostics and bioseparation. SEGNOS is developing ultra-fast and ultra-sensitive diagnostic platforms for infectious diseases, neurodegenerative disorders, and preventive healthcare. Its mission is to contribute to healthcare digital transformation, early disease detection, and the extension of healthy life expectancy through next-generation diagnostic technologies.

Technology & Business
SEGNOS has developed Therma-Max, a thermo-responsive magnetic nanoparticle, and Vira-Max, a PEG-responsive magnetic nanoparticle. These technologies enable both rapid magnetic separation and significantly enhanced detection sensitivity compared with conventional magnetic beads. The company is also developing AptIa, a highly sensitive diagnostic platform utilizing DNA aptamers, and ThermaLISA, a next-generation assay technology capable of performing diagnostic testing from a single drop of blood. Applications include infectious disease detection, Alzheimer's disease risk assessment, clinical diagnostics, high-throughput screening, and life science research.
