Elumalai EK, Kayalvizhi K, Silvan S - J Pharm Bioallied Sci (2014)

Bottom Line: The present study deals with the synthesis of silver nanoparticles (Ag-NPs) using the coconut water (C. nucifera) as the reducing agent.The synthesized Ag-NPs were predominately polydispersed.The approach of green synthesis appears to be cost efficient, ecofriendly and easy alternative to conventional methods of silver nanoparticle synthesis.

ABSTRACT

Aim of the study: The synthesis, characterization and application of biologically synthesized nanomaterials are an important aspect in nanotechnology.

Materials and methods: The present study deals with the synthesis of silver nanoparticles (Ag-NPs) using the coconut water (C. nucifera) as the reducing agent. The formation of Ag-NPs was characterized by UV-Visible Spectroscopy, Scanning Electron Microscopy (SEM), EDX, X-ray Diffraction (XRD) and FTIR spectroscopy.

Results: The synthesized Ag-NPs were predominately polydispersed. Crystalline nature of the nanoparticle in the face centered cubic (fcc) structure are confirmed by the peaks in the XRD pattern corresponding to (111), (200), (220) and (311) planes. Fourier Transform Infra-Red (FT-IR) spectroscopy analysis showed that the synthesized nanoparicles was capped with bimolecular compounds which are responsible for the reduction of silver ions.

Conclusion: The approach of green synthesis appears to be cost efficient, ecofriendly and easy alternative to conventional methods of silver nanoparticle synthesis.

Figure 4: XRD patterens of capped Ag-NPs synthesised using the coconut water (C. nucifera)

Mentions: The XRD result shows four distinct diffraction peaks at 38.12°, 44.27°, 64.27° and 76.23°, which are indexed for the planes (111), (200), (220) and (311) respectively of the face centered cubic Ag [Figure 4]. This data was matched with the database of joint committee on powder diffraction standards (JCPDS) for silver. Thus, the formation of Ag is confirmed. The additional peak obtained at 30° may be due to the bio-inorganic compounds and protein matters present in the coconut water (as evidenced from the intensity of the Bragg reflections of strong X-ray scattering points in the crystalline phase arise from proteins in the NPs synthesis).[31] Other minor peaks are due to noise only. The average grain size of the Ag-NPs synthesized by the greener method was calculated using Scherr's formula [d = (0.89λ×180°)/βcosθπ] and observed as 48 nm. Hence, the synthesized Ag was in nano size only.
