Bottom Line: In this study, gelatin was used for the first time as a reducing and stabilizing agent.It was found that with increasing temperature the size of nanoparticles is decreased.It was found that the particle size of Ag-NPs obtained in gelatin solutions is smaller than in gelatin-glucose solutions, which can be related to the rate of reduction reaction.

ABSTRACT
Silver nanoparticles (Ag-NPs) have been successfully prepared with simple and "green" synthesis method by reducing Ag(+) ions in aqueous gelatin media with and in the absence of glucose as a reducing agent. In this study, gelatin was used for the first time as a reducing and stabilizing agent. The effect of temperature on particle size of Ag-NPs was also studied. It was found that with increasing temperature the size of nanoparticles is decreased. It was found that the particle size of Ag-NPs obtained in gelatin solutions is smaller than in gelatin-glucose solutions, which can be related to the rate of reduction reaction. X-ray diffraction, ultraviolet-visible spectra, transmission electron microscopy, and atomic force microscopy revealed the formation of monodispersed Ag-NPs with a narrow particle size distribution.

f4-ijn-6-569: X-ray diffraction patterns of AGG60 and AG60.

Mentions: The AFM results display the surface morphology of the monodispersed Ag-NPs formed in gelatin and gelatin–glucose media. As observed in Figure 3, the value determined by the AFM was close to that determined by the TEM, and the films of gelatin and gelatin–glucose containing Ag-NPs showed a dense and uniform packed structure. Thus, the Ag-NPs and gelatin and Ag-NPs and gelatin–glucose films could provide a biocompatible and rough surface for biological uses, eg, cell immobilization. Figure 4 shows the XRD patterns of AG60 and AGG60, which show the synthesis of the silver crystalline structure. The XRD peaks at 2θ degrees of 37.9, 44.1, 64.3, and 76.9 and can be attributed to the (111), (200), (220), and (311) crystalline planes of the face centered cubic (fcc) crystalline structure of metallic silver, respectively (JCPDS file No. 00-004-0783).
