Green synthesis and properties of silver nanoparticles in sulfobutylether-β-cyclodextrin aqueous solution

Spherical and monodisperse silver nanoparticles (AgNPs) were obtained in aqueous solution at neutral pH in the presence of sulfobutylether-beta-CD (SBE-beta CD) by using an eco-friendly approach. Their stability and size were determined by spectroscopic analysis and light scattering measurements. The SBE-beta CD molecules are highly distributed around the AgNPs as observed in the SEM-EDX images and tend to act as stabilizers by preventing their aggregation in solution as suggested by the zeta potential measurements. Furthermore, the dissolution of the investigated nanoparticles was tested by oxidation in the Fenton-like reaction.
