Nanocrystals to deliver oxygen to brain tumours

Glioblastoma, the most widespread and lethal primary brain tumor in adults, is notoriously difficult to treat due to the surrounding lack of oxygen essential to the effectiveness of current treatment.

A team of CNRS and University of Caen Normandie researchers have successfully delivered the necessary oxygen to the tumor using zeolite nanocrystals. While inhaling oxygen supplies only healthy brain tissue, the nanoparticles are able to target the tumor itself, whose growth causes damage to the barrier separating the brain from the circulatory system. This allows nanocrystals delivered intravenously to reach the tumor.
