Background: Biosynthesis of nanoparticles has attracted the attention of the scientific community in nanotechnology and biotechnology due to their extensive application in the area of material sciences and medicine. Nowadays, despite a various application of nanomaterial’s, there is a little information about their impact on human health. In this study, we investigated the comparative study on cytotoxicity effect of biological and commercial synthesized nanosilver on human gastric carcinoma (AGS) and normal lung fibroblast (MRC-5) cell lines.
Methods: The current experimental study was carried out in Islamic Azad University, East Tehran Branch, from April to November 2014. The biological synthesis of nanosilver was obtained from Eucalyptus plant extract as a reducing agent. Further to more analysis, morphological study on size and shape of developed biological nanosilver was characterized by performing scanning electron microscopy and dynamic light scattering. AGS and MCR-5 cell lines were treated with various concentration of nanosilver for 24, 48 and 72 hours. Finally, the cell viability was evaluated by using MTT assay.
Results: The results show that the nanosilver exerts a dose-dependent inhibitory effect on viability of cells. At 100µg/mL of commercial and biological synthesized nanosilver, the viability of AGS was reduced to 7.47±0.002% (P=0.002) and 3.65±0.01% (P=0.003) after 72 hours, respectively. In addition, the viability of MRC-5 at the same condition was reduced to 10.27±0.19% (P=0.001) and 9.16±1.53% (P=0.002), respectively.
Conclusion: Based on a thorough literature surveys, the present study is the first research about biosynthesis of nanosilver using Eucalyptus plant extract. This eco-friendly and cost effective method can be used for large scale production of silver nanoparticle. In addition, based on the current obtained data, commercial and biological synthesized nanosilver can more inhibitory effect on cancer cells compared to the normal cells. Hence, silver nanoparticles might be used as a new strategy for treating many human cancers. However, further studies are necessary to ascertain their potential as anticancer agents.
