Figure 9

SEM micrographs of goethite (a) and goethite-Bt toxin (b). (a₁), (a₂), (a₃), and (a₄) mean that the magnification for goethite is 5000x, 10000x, 20000x, and 30000x, respectively; (b₁), (b₂), (b₃), and (b₄) mean that the magnification for goethite-toxin complexes is 5000x, 10000x, 20000x, and 30000x, respectively.
