Control of size and shape is a challenge in nanoparticle synthesis. Synthetic and biosynthetic (both extracellular and intracellular) methods are used to prepare silver nanoparticle (SNP). In this study, the behavior of three strains of Staphylococcus aureus (S. aureus) was investigated in the presence of silver nitrate intra- and extracellularly. S. aureus strains biosynthesized SNPs intracell...

Interaction of Chrysosporium sps. and Aspergillus sps. with aqueous AgNO3 was investigated for synthesis of silver nanoparticles. Biological reduction and extracellular synthesis of silver nanoparticles in 28 hour at 270C and pH 5.6 was done. The nanometallic dispersion was characterized by surface plasmon absorbance measuring at 424 – 530 nm for Ag nanop...
