PROJECT TITLE :

Photochemical Reduction as a Green Method for the Synthesis and Size Control of Silver Nanoparticles in κ-Carrageenan

ABSTRACT:

An eco-friendly photochemical method for getting ready silver nanoparticles (Ag-NPs) during a natural polymer (κ-carrageenan) was successfully developed and is reported during this study. The Ag-NPs have been synthesized via a photochemical technique by using UV-irradiation, silver nitrate and κ-carrageenan as a reducing agent, a silver precursor and a stabilizer at space temperature, at totally different irradiation time. The formation of Ag-NPs was improved by UV-vis spectroscopy where surface plasmon absorption maxima was observed at 420-430 nm. Transmission electron microscopy (TEM) data and the size distribution were in an agreement with the finding from the UV-vis spectra. Scanning electron microscope knowledge illuminated the changes within the surface of κ-carrageenan. Fourier transform infrared spectra indicated the interactions between Ag-NPs and κ-carrageenan. In addition, the Ag-NPs were characterised by X-ray diffraction (XRD). The peaks within the XRD pattern showed that the Ag-NPs possessed an FCC structure. The green ways by using an eco-friendly stabilizer and reducing agent provide green and economic attributes to the current paper. These results demonstrate the successful synthesis of Ag-NPs in κ-carrageenan by using UV-irradiation as a green and a photochemical reducing methodology. Ag-NPs were obtained by using UV-irradiation at completely different times at area temperature, where increasing irradiation time corresponded to the formation of smaller a lot of spherical Ag-NPs. The synthesized Ag-NPs realize applications as bacteria inhibitors and will be applied within the medical field.
