Cytotoxicity Property of Biologically Synthesized Gold Nanoparticles from Aqueous Leaf Extract of Calotropis procera (Apple of Sodom) on MCF-7 Cell Line
Journal Title: Journal of Advances in Medicine and Medical Research - Year 2016, Vol 15, Issue 12
Abstract
The use of gold nanoparticle in drug delivery has emerged as a promising avenue to reduced toxicity and frequency of dosage while maintaining therapeutic effects and biocompatibility. Therefore, the possibility of developing eco-friendly metallic gold nanoparticles is evaluated. To achieve this, aqueous leave extracts of Calotropis procera was used to synthesis gold nanoparticles and its cytotoxic effect was investigated. The gold nanoparticles (AuNPs) produced were characterized using Ultra Violet–Visible spectroscopy, Zeta-sizer nano, High Resolution Scanning Electron Microscopy (HRSEM), Energy-Dispersive X-ray (EDAX) spectroscopy and Fourier Transmission Infrared (FTIR) spectroscopy. The cytotoxic ability of the synthesized gold nanoparticles was evaluated on MCF-7 cell using MTT assay. The result of Ultra Violet–Visible spectroscopy showed development of gold nanoparticle reaction at 550 nm of Surface Plasmon Resonance and average particle size of 45 nm was confirmed using nano Zeta-sizer. EDAX profile result suggested the presence of gold at 2.30ke while FTIR result confirms the presence of biomolecules serving as reducing and capping agents on the synthesized gold nanoparticle with a strong signal at 3426 cm of the hydroxyl group of alcohol or phenol. The cytotoxic effect of the synthesis gold nanoparticles shows cell viability decreased as the concentration of AuNPs increased from 0.156 mg to 5 mg with an IC50 of 0.312 mg/l. In conclusion, this study demonstrated the bioreductive capability of aqueous leaf extract of Calotropis procera to produced gold nanoparticle and its cytotoxicity effect on MCF-7cell line.
