TEM measurements were used to determine the morphology and shape of nanoparticles. Silver nanoparticles were synthesized by the cell free filtrate of Streptomyces sp. II, after reacting with silver nitrate. The well dispersed nanoparticle was confirmed by the occurrence of silver nanoparticles which showed that the size of particles range from 65 to 80 nm. The nanoparticles were observed as spherical in shape. Low magnification TEM micrographs revealed that the particles are spherical in shape and uniformly distributed (monodispersed) without significant agglomeration as represented by Figure 2a. The particle size of microbially synthesized silver nanoparticles shows that the particle size is smaller(10 to 20 nm) compared to the chemically synthesized silver nanoparticles(60-80 nm) as denoted by the Figure 2b.
