Synthesis of silver nanorods using Coscinium fenestratum extracts and its cytotoxic activity against Hep-2 cell line

Silver nanorod has attracted considerable interest due to its potential applications in display technologies, thermoelectric and electronic devices, optoelectronic devices and biomedicine. In this study, crystalline silver nanorods were successfully prepared from AgNO3 using Coscinium fenestratum extract as a reducing agent. The products were characterized by UV–visible spectroscopy, FTIR (Fourier-transform IR) spectroscopy and SEM (scanning electron microscopy) analysis. Bundle-like nanostructures were observed by SEM analysis and the diameters of the nanorods were found to be in the range of 28.5–68.0 nm. The MTT assay results revealed that silver nanorod exhibit significant cytotoxic effect on HEp-2 cells.
