Abstract:
Nanodiamonds (NDs) have unique optical, thermal and mechanic properties. They also have the advantage of high biocompatibility, which makes them appropriate to biomedical applications. Recently a protective effect against γ-irradiation of carboxylated nanodiamonds (cNDs) has been reported on erythrocytes. The structural, mechanical thermal and optical properties transformation of cNDs dispersed in water and exposed to γ-radiation were analyzed. Commercial detonation NDs and cNDs were analyzed by different techniques including transmission electron microscopy (TEM), scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS), Raman spectroscopy and atomic force microscopy (AFM) after and before treatments with 20, 40, 60, 120 and 240 Gy of γ-irradiation. Here we report the water interaction with cNDs during radyolisis at different degree.
