Fig. 5From: Effect of sp3/sp2 carbon ratio and hydrodynamic size on the biodistribution kinetics of nanodiamonds in mice via intravenous injectionRepresentative TEM images of the lung at day 7 post-injection of lowND. (a) lowND are clustered in alveolar capillaries. (b) The higher magnification images of the red circle area of Fig. 4a suggest particles are stuck with the proteinous materials. (c) The higher magnification images of Fig. 4b. (d) SAED pattern of the ND cluster indicates electron diffraction spots (yellow circles), which suggests that particles are exogenous with the crystal structureBack to article page
