Novel and facile synthesis of silver nanoparticles using Albizia procera leaf extract for dye degradation and antibacterial applications.

This project is focuses on novel, cost effective and simple plant mediated synthesis of silver nanoparticles (Ag-NPs) using leaf extract of Albizia procera. The optical, structural and physical properties of green synthesized Ag-NPs have been investigated by UV-Visible spectroscopy, X-ray Diffraction (XRD) and Atomic Force Microscopy (AFM), respectively. Prepared Ag-NPs are spherical in shape and crystalline in nature with an average size of 6.18 nm. Ag-NPs have showed promising potential in removal of organic pollutant methylene blue (MB) dye. Careful investigation on the removal of dye as a function of contact time, UV light and exposure time, dose of nanoparticles, temperature and pH have also been carried out. Moreover, Ag-NPs exhibit outstanding antibacterial activities against gram negative Escherichia coli (E. coli) and gram positive Staphylococcus aureus (S. aureus) bacterial pathogens.

A review on green synthesis of silver nanoparticles and their applications.

Development of reliable and eco-accommodating methods for the synthesis of nanoparticles is a vital step in the field of nanotechnology. Silver nanoparticles are important because of their exceptional chemical, physical, and biological properties, and hence applications. In the last decade, numerous efforts were made to develop green methods of synthesis to avoid the hazardous byproducts. This review describes the methods of green synthesis for Ag-NPs and their numerous applications. It also describes the comparison of efficient synthesis methods via green routes over physical and chemical methods, which provide strong evidence for the selection of suitable method for the synthesis of Ag-NPs.
