2011 – ECCO Abstract – NBTXR3 as promising cancer therapy – Magiorella et al.

We created and developed NBTXR3 nanoparticles with a crystalline hafnium oxide core which provide high electron density structure and inert behavior in biological media. NBTXR3 nanoparticles’ characteristics, size, charge and shape, allow for efficient interaction with biological entities, cell membrane binding and cellular uptake. The nanoparticles were shown to form clusters at the subcellular level in tumor models. Of most importance, we show NBTXR3 intratumor bioavailability with dispersion of nanoparticles in the three dimensions and persistence within the tumor structure, supporting the use of NBTXR3 as effective antitumor therapeutic agent.
