    The near-edge spectra (e.g. figure 1, top) suggests that the gold in the plant samples and the agar growth media is present as elemental gold [Au(0)], and that alfalfa therefore has the ability to take up Au(0) from the media, and transport it throughout the plant. Quantitative analysis of the EXAFS (figure 1, bottom) indicates that gold is present as gold particles. As expected from the FCC

  • Green synthesis of gold nanoparticles using plant extract

    Alfalfa can accumulate gold and store it in their leaves and stems biomasses as discrete nanoparticles of pure metal [48]. In recent years, various plants have successfully been used and reported for effective and rapid extracellular synthesis of gold, silver and copper nanoparticles such as broth extracts of neem [49], Aloe Vera [50-51], Arena sativa [52], wheat [53], alfalfa [54], geranium

  • The effects of three types of alfalfa plants ( Medicago

    Phytomining involves bioharvesting of metals from high biomass crops grown in soil substrates. This process has the potential for economic exploitation of low-grade mineralized soils (e.g., gold), which are too poor for conventional mining of metals. There is a lot of evidence that supports the synthesis of gold nanoparticles in living plants. In this study, the bioreduction of Au ions to Au nanoparticles (AuNPs/GNPs) by three types of Iranian alfalfa plants
