Application of Phytotests to Study of Environmental Safety of Biologicaly Synthetised Au and Au/ZnO Nanoparticles Using Tanacetum parthenium Extract

Abstract Due to their small sizes and high reactivity, nanoparticles have a completely different toxicity profile than larger particles, it is difficult predict potential ecological impact. There need for broad ecotoxicological studies of nanomaterials in order specify environmental impact ensure safe application nanotechnology products. In this work, we assessed the Au Au/ZnO metal obtained with use Tanacetum parthenium (herba) extract. The were characterized by UV–Vis spectrophotometry (UV–VIS), Transmission electron microscopy (TEM), Atomic force (AFM), Fourier transform infrared spectroscopy (FTIR). assess biologically synthesized nanoparticles, used seeds various plants: Lepidium sativum , Linum flavum, Zea mays, Salvia hispanica -chia, Lupinus angustifolius Petroselinum crispum subsp. Crispum, Beta vulgaris Phaseolus . vitro phytotests showed that gold at specific range concentrations all plants stimulated growth. highest growth activity was exhibited solution concentration 0.300 mg/ml towards corn (Aw ≈ − 135 ± 16) flax 44 10). Only parsley IC50 determined 0.57 mg/ml, but solutions 0.030 0.150 also plant had toxic effect applied study.
