Extracellular Biosynthesis of Copper and Copper Oxide Nanoparticles by Stereum hirsutum, a Native White-Rot Fungus from Chilean Forests

Figure 2

Transmission electron microscopy (TEMs) of (a) copper and/or copper oxide nanoparticles and (b) the nanoparticles embedded in the polymer. These nanoparticles were biosynthesized by the mycelium-free extract of S. hirsutum in the presence of CuCl2 (5 mM) after 3d at pH 9.0.
