| description | Background and Objectives: Nanotechnology is an interesting research area due to production of nanoparticles of different sizes, shapes, chemical compositions, dispersity, and their numerous applications for human being. Creation, manipulation, and use of metallic nanoparticles is of great importance due to reduction of dimensions, and thus having unique thermal, optical, and electronic characteristics. The biosynthesis methods of nanoparticles are prioritized compared to chemical and physical procedures because of lower energy and time costs. Green synthesis of nanoparticles is an eco-friendly method, in which natural solvents are used. In this study, the phytosynthesis of silver nanoparticles by Malva neglecta, was investigated.
Methods: The extract of Malva neglecta was used as a reducing agent for biosynthesis of silver nanoparticles. By adding silver nitrate in concentration of 20mM to the extract, the reaction was done at room temperature, that the color change of the extract from pale yellow to dark brown showed the generation of silver nanoparticles.
Results: In this study, the formation of silver nanoparticles was confirmed (by the presence of an absorption peak at 450 nm) using a spectrophotometer. The size and morphology of silver nanoparticles were determined using scanning electron microscopy. The shape of particles was spherical and their average size was about 20nm.
Conclusion: The results of this research showed that silver nanoparticles can be produced by an eco-friendly biological method and without using any harmful chemicals. |
