Figure 1. Characterization of GNPs, ALD, and GNPs-ALD.
TEM images of the GNPs (A) and GNPs-ALD (B) and their dynamic light scattering intensities (C,D). Ultraviolet-visible spectrophotometer graph of GNPs and GNPs-GNPs (E), ATR-FTIR spectrum (F) and TGA (G) of GNPs, ALD and GNPs-ALD. The tibias of mice were immersed in either blank (control), GNPs, or GNPs-ALD solutions for 24 h. These were measured by using FE-SEM and energy dispersive x-ray spectroscopy (EDX). The results of EDX (H) and FE-SEM images of the measured place by EDX (I) contained nothing, (J) contained GNPs, (K) contained GNPs-ALD, (L) enlargement of (K) at the tibias. Scale bars are 100 nm (A,B), 100 μm (I–K) and 200 nm (L).
