New Bismuth Germanate Oxide Nanoparticle Material for Biolabel Applications in Medicine

Figure 3

AFM image of BGO nanoparticles. The red and green lines are the AFM section analysis that show nanoparticles size (a) before and (b) after the BSA functionalization. TEM images presented spherical particles, and the size observed by the AFM technique also corresponded to spheres. Thus, the increment in size after functionalization is presumably related to the formation of a protein shell over the BGO particles.
