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 mg/mL for E. coli and 20 mg/mL for S. typhi and B. cereus with significance difference. Toxicity, proliferation and antimetastatic 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 lg/mL and 5 lg/mL inhibit by 96% and 75%, respectively. The synthesized FILE-AgNPs are remarkable candidates for treatment of cancer cases and other cancer related cases.
