摘要：

Silver nanoparticles are synthesized in the medium of an aqueous cysteine-silver solution at different NEuroDe values using sodium borohydride as a reductant. Dynamic light scattering, electron spectroscopy, and transmission electron microscopy are applied to find that the size and stability of nanoparticles in this system depend on NEuroDe, which is regulated by alkali, and on the concentration of the cysteine-silver solution. Under certain conditions, it is possible to obtain a unimodal distribution for silver nanoparticles with an average size of similar to 40 nm.
