摘要

The development of reliable processes for the synthesis of silver nanomaterials is an important aspect of current nanotechnology research. In this work, silver nanoparticles were produced in a bioreactor by Escherichia coli (E. coli). For this purpose, a process was designed and silver nanoparticles at a scale larger than laboratorial scale were produced by considering optimum conditions and using E. coli. This research for the first time was carried out at a scale larger than laboratory scale indicating ability to produce nanoparticles at a large scale using microorganisms. In addition, UV-vis spectroscopy, atomic absorption spectroscopy (AAS), transitional electron microscopy (TEM) and dynamic light scattering (DLS) were employed to investigate characterisation of nanoparticles.
