About Magnephy
Magnephy is a Stockholm-based start-up that combines advanced microscopy and AI to explore the nanoscale of biology.
Founded in 2023 as a spin-off from KTH Royal Institute of Technology/SciLifeLab after nearly a decade of research on novel methods within microscopy techniques.
We now offer our technology as a service to pharmaceutical companies, and our mission is to provide quantitative nanoscale insights into pharmaceutical efficacy, mechanism of action, and targeting directly in tissue samples.
Using high-resolution microscopy and advanced image analysis, we visualize treatment effects such as changes in cell structure, biomarker distribution, and tissue organization. These insights make it easier to evaluate efficacy and guide the next step in development.
