Figure 2

Transmission electron microscopy of TiO 2 nanoparticles synthesized by B. mycoides . Biosynthesized nanoparticles before (a) and after successive washings in water (b). The inset in (a) shows the spherical morphology of TiO2 nanoparticles. The inset in (b) shows the size distribution histogram of nanoparticles. Arrow heads indicate individual NPs. Images were obtained with a 100,000× magnification.
