- To utilize natural polymeric media for the stabilization and reduction of silver ions.
Main Methods:
- Synthesis of colloidal Ag-NPs in an aqueous solution using silver nitrate, gelatin, and glucose.
- Characterization of Ag-NPs using ultraviolet-visible (UV-vis) spectroscopy, transmission electron microscopy (TEM), X-ray diffraction (XRD), and atomic force microscopy (AFM).
- Evaluation of nanoparticle properties at varying reaction times.
Main Results:
- Successfully synthesized stable colloidal Ag-NPs using a green chemistry approach.
- Characterization data (UV-vis, TEM, XRD, AFM) confirmed the formation and properties of the Ag-NPs.
- The size distribution and nanostructure of the Ag-NPs were consistent with spectroscopic results.
Conclusions:
- The developed method offers a green and economical route for Ag-NP synthesis.
