【 摘 要 】

Scientists use biological procedures as ecofriendly and cost-effective routes to synthesis nanoparticles and nanomaterials. In this work, the biological attitude was aimed at the production of nanoparticles by Haplophyllum obtusifolium watery extract. Several procedures used to describe fabricated nanoparticles are transmission electron microscopy, ultraviolet–visible (UV–vis) spectrometry, Fourier transform infrared spectroscopy, and X-ray diffraction. UV–vis technique indicated a sharp peak in area 416 nm and transmission electron microscopy pictures show that the shape of the nanoparticles is spherical and the mean diameter of the synthesised nanoparticle is 13 nm. The silver and silver oxide-nanoparticles (Ag/Ag 2 O-NPs) exhibited antimicrobial properties against positive/negative infective bacteria for instance Staphylococcus aureus/Pseudomonas aeruginosa, Escherichia coli. The biosynthesised nanoparticles show anticancer activity against liver cancer cell (HepG2) which depend on time and concentrations. Also, the synthesised Ag/Ag 2 O-NPs act as a green catalyst because of accelerated degradation of stable and organic dye. Consequences established this protocol as easy, fast, nontoxic and alternative conventional physico-chemical approache.
