Green synthesis of silver nanoparticles using Delonix regia leaf extract and evaluation of their antimicrobial efficacy
Journal Title: World Journal of Pharmaceutical Sciences - Year 2017, Vol 5, Issue 3
Abstract
The green synthesis of nanoparticles is eco-friendly. Nanoparticles are of great scientific interest as they are, in effect, a bridge between bulk materials and atomic or molecular structures. The synthesised nanoparticles are playing an important role in the field of nanotechnology. Synthesized nanoparticles were characterized using UV-Visible Spectrophotometer used to predict that where the synthesis has been done or not. The absorbance of UV- Vis analysis is 455 nm. FTIR- Fourier Transform Infrared Spectroscopy with different wave number and it has determined by the functional group data analysis. SEM- Scanning Electron Microscopy, Particle size analyser shows that the particles are in 62 nm. The Photoluminescence spectrum showed the excitation peak at 650 nm. The antibacterial activities are carried out against bacteria and fungi by using disc diffusion method. The present study states that the green synthesis of silver nanoparticles of Delonix regia is having many advantageous properties and antimicrobial activity. The synthesized nanoparticles can be used in the field of pharmaceutical industry to produce medicine.
