Toxicity concerns are always utmost to consider when developing tools for the clinic! Thus far, all studies regarding nanodiamonds have shown biocompatibility and non-toxicity. Coming from a research background and having done a number of in vivo studies myself, these studies we plan to repeat with each targeted version of the nanodiamond (particle + ligand such as antibody) before reaching the clinic. To clarify, we are at the pre-clinical level currently.
