Silver Nanoparticles from Switenia mahagony : green Synthesis and Characterisation

The synthesis of metal and semiconductor nanoparticles is an expanding research area due to the potential applications for the development of novel technologies. In this work, we describe a cost effective and environment friendly technique for green synthesis of silver phyto nanoparticles and their antibiogram from 3mM silver nitrate solution through the extract of Switenia mahagony as reducing as well as capping agent. In the process of synthesising silver nanoparticles, we observed a rapid reduction of silver ions leading to the formation of stable crystalline silver nanoparticles in the solution. The herbal leaves and their medicinal properties were already discussed in varieties of ayurvedic studies. The synthesis of silver phyto nanoparticles were prepared by adding silver nitrate solution solution (3mM) to the plant extract. Nanoparticles were characterised using UV-Visible absorption spectroscopy, FTIR, XRD, XRF, TEM AND SEM analysis. The biomass of plants produces their nanomaterials by a process called bio mineralisation. It was concluded from the above studies that 3 mM concentration of silver nanoparticles showed the best concentration amongst the various concentrations prepared and also their characterisation showed that these nanoparticles synthesised were mostly globular in structure, and proved to have the functional groups in the terminal ends as well as showed sharp peaks by XRD studies.
