ID17 and gold nanoparticles production. (A) Spectra of gold nanoparticles production in the course of time at 0 (), 3 (), 9 () and 16 (Δ) h of incubation; (B) Transmission electron micrograph. Black spots corresponding to gold nanoparticles and arrow show digital zoom where quasi-hexagonal shapes are shown; (C) Gold nanoparticles produced by the microorganism on a copper grille (scale bars correspond to 200 nm). (D) Histogram distribution (obtained using Sigma Plot 11.0 software) that shows the particle size distribution (obtained with NIS-Elements D 3.10 software).
