Biological synthesis of silver nanoparticles by using Viola serpens extract
Journal Title: Asian Pacific Journal of Tropical Disease - Year 2016, Vol 6, Issue 3
Abstract
Objective: To formulate a biological approach for the biological synthesis of silver nanoparticles using aqueous extracts of leaves of Viola serpens which is considered as a ecofriendly method as it does not include any harmful chemicals. Methods: The synthesized silver nanoparticles were characterized by using UV-vis spectroscopy analysis, scanning electron microscopy analysis and X-ray diffraction analysis. Results: Scanning electron microscopy analysis study revealed that synthesized silver nanoparticles were of an average size of 80–90 nm. Crystalline nature of synthesized silver nanoparticles was confirmed by X-ray diffraction analysis. Conclusions: The leaves of Viola serpens can be a potent source for the biological synthesis of silver nanoparticles. The outcome of the study can lead to the development of a novel drug for biomedical field.
