A Dartmouth Spin-Off

In 2015 Sol Diamond, Lidia Valdés and Brad Ficko set out to revolutionize medical diagnostics and founded Lodestone Biomedical out of a basement laboratory at Dartmouth College. Early on Lodestone aimed to bring low-cost, high-sensitivity magnetic detection methods into the medical device market. Our goal was not to incrementally improve existing diagnostics, but to measure what was previously impossible to detect.In close collaboration with advisors and clinical collaborators, we refined our magnetic detection methods over the years to the cytokine monitoring system we offer today.

About the Name

Lodestone (/ˈlōdˌstōn/, noun)

A naturally occurring magnetic rock composed of the mineral magnetite.
In ancient times, explorers used lodestones to make magnetic compasses for navigation on land and at sea. This extraordinary history of magnetite is reflected in the name "Lodestone", which means "leading stone.”
Today magnetite forms the core of Lodestone Biomedical's magnetic nanoparticle platform technology for in vivo biomarker monitoring in immuno-oncology. Our biosensors serve as a "molecular compass" for cancer immunotherapy drug development from bench to bedside.

Learn more about the history of the magnetic mineral on the website of the National High Magnetic Field Laboratory.
