Biomediated synthesis of nanoparticles has received much attention due to innovative and unique properties in various fields. In the present study, using ficus carica extract, nickel nanoparticles were synthesized. NiO-NPs were characterized using UV-visible spectroscopy, X-ray diffraction (XRD), energy dispersion X-ray (EDX) and scanning electron microscopy (SEM). X-ray diffraction confirmed the crystalline nature of the nanoparticles. SEM revealed the morphological features with a nanoparticle size of 20-25 nm. FTIR analysis confirmed nanoparticle capping by chemicals present in ficus carica. Later, EDX confirmed the elemental composition of the nanoparticles. The biosynthesized nanoparticles showed tremendous antibacterial activity against various bacterial strains. Overall, it was concluded that NPs played a vital role in various biological assays, but extensive in vivo and cytotoxic research is needed.
