Table 1 Summary of the physical and chemical properties of diamond (DN), graphite (GN), and graphene oxide (GO) nanoparticles

From: Biodistribution of a High Dose of Diamond, Graphite, and Graphene Oxide Nanoparticles After Multiple Intraperitoneal Injections in Rats

  DN GN GO
Shape Spherical Spherical Irregular
Average size (nm) 3–4 3–4 8–25
Zeta potential (mV) −15.8 ± 0.55 12.5 ± 0.43 −8.8 ± 0.25
  1. Shape was estimated upon analysis of transmission electron microscopy pictures. Zeta potential and average size were measured by a Zetasizer. The results are means ± standard deviation
