Nanobiotix is a nanomedicine company dedicated to the development of new treatments for cancer based on the combined application of nanotechnologies and biotechnologies. Nanobiotix has developed a new class of therapeutics based on nanoparticles, NanoXray™ therapeutics. They consist of inert nanoparticles designed to enter tumor cells. Upon activation by a standard dose of radiation, they release a tremendous amount of energy that destroys cancer cells, whilst the surrounding healthy tissues are preserved and receive the same dose of radiation as in standard radiotherapy. Founded in 2003, the company is based in Paris.
