Effect of sp3/sp2 carbon ratio and hydrodynamic size on the biodistribution kinetics of nanodiamonds in mice via intravenous injection.
Background: Nanodiamonds (NDs) have gained a rapidly growing interest in biomedical applications; however, little is known regarding their biokinetics owing to difficulties in measurements and limited synthesis/purification technologies. In this study, we investigated the distribution kinetics of detonation-synthesized NDs in mice via intravenous injection to evaluate the parameters that determine the behavior of the particles. We prepared two distinctive NDs that controlled the sp3/sp2 carbon ratio and particle size by coating them with serum proteins. The four control samples were intravenously injected into mice, and tissue distribution and clearance were evaluated at 30 min and 1, 7, and 28 days post-injection.
Results: The sp3/sp2 carbon ratio showed no correlation with the organ distribution of the NDs. However, hydrodynamic size showed an excellent correlation with organ distribution levels: a negative correlation in the liver and positive correlations in the spleen and lungs. Furthermore, the deposition levels of NDs in the lung suggest that particles smaller than 300 nm could avoid lung deposition. Finally, a similar organ distribution pattern was observed in mice injected with carbon black nanoparticles controlled hydrodynamic size.
Conclusions: In conclusion, the tissue distribution of NDs is modulated not by the sp3/sp2 carbon ratio but by the hydrodynamic size, which can provide helpful information for targeting the tissue of NDs. Furthermore, the organ distribution pattern of the NDs may not be specific to NDs but also can apply to other nanoparticles, such as carbon black.
期刊介绍:
Particle and Fibre Toxicology is an online journal that is open access and peer-reviewed. It covers a range of disciplines such as material science, biomaterials, and nanomedicine, focusing on the toxicological effects of particles and fibres. The journal serves as a platform for scientific debate and communication among toxicologists and scientists from different fields who work with particle and fibre materials. The main objective of the journal is to deepen our understanding of the physico-chemical properties of particles, their potential for human exposure, and the resulting biological effects. It also addresses regulatory issues related to particle exposure in workplaces and the general environment. Moreover, the journal recognizes that there are various situations where particles can pose a toxicological threat, such as the use of old materials in new applications or the introduction of new materials altogether. By encompassing all these disciplines, Particle and Fibre Toxicology provides a comprehensive source for research in this field.
