Synthesis, characterization, antimicrobial and antimetastatic activity of silver nanoparticles synthesized from Ficus ingens leaf.

Cancer incidence is still increasing due to inadequate responsive treatments. Inertness and biocompatibility of nanoparticles synthesized using plant extracts have shown therapeutic applications and make it to be a good anti-cancer candidates. This study is a recent novel spotlight that synthesized silver nanoparticle from Ficus ingens leaf extract (FILE) and studied its anti-metastatic and anti-bacterial activity. The chemical and surface analysis of the synthesized FILE silver nanoparticles (FILE-AgNPs) was studied using UV-visible, Fourier transform infrared (FTIR), X-ray diffraction (XRD), zeta sizer, atomic force microscopy (AFM) and scanning electron microscopy (SEM). Gas chromatography mass spectrometric (GC-MS) and quantitative photochemical analyses were also carried out. The antimicrobial activity of FILE-AgNPs was found to be effective with MIC of 10 µg/mL for E. coli and 20 µg/mL for S. typhi and B. cereus with significance difference. Toxicity, proliferation and anti-metastatic potential of FILE-AgNPs were studied on MDA-MB 231 cell models using tryphan blue, MTT and wound heal assay, respectively. FILE-AgNPs showed the ability to inhibit metastasis of MDA-MB 231 cells in dose-dependent manner in which 10 μg/mL and 5 μg/mL inhibit by 96% and 75%, respectively. The synthesized FILE-AgNPs are remarkable candidates for treatment of cancer cases and other cancer related cases.
