3N Bio AB

3N Bio AB is a Swedish life science startup and spin-off from SciLifeLab and Karolinska Institutet that develops diagnostic technologies to combat antimicrobial resistance. The company utilizes microbial metadegradomics to analyze RNA degradation signatures, enabling the direct, rapid measurement of bacterial growth and species-specific responses to antibiotics at the molecular level. By monitoring how bacterial cells recycle mRNAs, their approach functions without the need for complex experimental procedures, cell culture, or bacterial isolation, offering a streamlined method to detect antibiotic resistance within minutes.

The company aims to address the global threat of antibiotic-resistant bacteria and multidrug-resistant fungi by accelerating diagnosis and providing actionable information for antibiotic treatments. This technology is intended to support more personalized and rational antibiotic usage, potentially improving patient survival rates and containing the spread of resistant infections. Supported by research grants and scientific publications in journals like Nature Microbiology, 3N Bio is currently focused on applying its technology to develop simplified diagnostic kits for bacterial infections.
