Fig. 4

Visualization by digital camera of the biodistribution of diamond nanoparticles after multiple intraperitoneal injections into rats. Solid aggregates were lodged in injected body regions (a, b, c), small dots of nanoparticle aggregates were also present in abdominal lipid tissue (e) and mesentery (d). Black arrows indicate diamond nanoparticle aggregates. The macroscopic structure of the kidney (f), lungs (g), heart (h), spleen (i), and liver (j) were also examined. There were no macroscopic pathological features on the organs
