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 5: FTIR spectrum recorded by making KBr with synthesized Ag-NPs using the coconut water (C. nucifera)

Mentions: FTIR measurement was carried out to study the interaction of the nanoparticles and to identify the possible biomolecules in coconut water responsible for capping leading to efficient stabilization of the NPs. The intense IR bands [Figure 5] are observed at 3398, 1613, 1368, 1213 and 1069 cm-1. The bands observed at 3398 and 1613cm-1 are assigned to the stretching vibrations of the C-H and C-C bonds, respectively. The broad band at 1213 cm-1 is due to C-O and C-H stretching modes. The absorption bands located at 1368 may be attributed to C-H, NO3 and C-N stretching modes,[34] respectively. The bonds or functional group such indicates that's. Therefore, it may be assumed that water soluble compounds such as flavonoids, silver nanoparticles synthesized using the coconut water surrounded by some proteins and metabolites such as terpenoids, flavonoides which are capping ligands of the nanoparticles.
