The chemical components mainly including flavonoids diterpenoids alkaloids steroids and polysaccharides were involved in bioreduction of gold nanoparticles 34. Alfalfa plants were used for synthesis of gold particles with an approximate size of 4 nm

Nanoparticle Synthesis Using Plants. Plants have shown great potential in the detoxification and accumulation of heavy metals over the years. One of the first reports on effective synthesis of gold and silver nanoparticles used alfalfa plants grown in a target metal-salt-rich environment.
of gold nanoparticles in the size range from 6.75-57.91 nm 26. The fruit peel extract of Punica granutum was used to synthesis the gold nanoparticles for cancer targeted drug delivery 27. Hibiscus leaf extract was used to synthesise gold nanoparticles of different size and shape with average particle size of 13 nm 28.
Unique properties of gold nanoparticles AuNPs can be achieved by manipulating their geometries. However it is not known if the shapes and sizes of AuNPs can be modulated in planta. Here we evaluated the accumulation of gold across taxonomically diverse plant species alfalfa cucumber red clover ryegrass sunflower and oregano.
May 20 2014 Nanoparticles could be industrially harvested. For example alfalfa plants grown in an AuCI 4 − rich environment showed absorption of gold metal by the plants. The gold nanoparticles can be mechanically separated by dissolving the organic material plant tissue following harvest. 263
reduced to Au 0 by alfalfa plants. Oat Avena sativa biomass was also found to recover Au III ions from aqueous solutions and reduce Au III to Au 0 forming Au nanoparticles Armendariz et al. 2004 2009. Synthesis of nano-gold has also been reported in algae including Chlorella vulgaris Ting et al. 1995 Sargassum

Scientists use alfalfa plants to harvest nanoparticles of gold. Ordinary alfalfa plants are being used as miniature gold factories that one day could provide the nanotechnology industry with a continuous harvest of gold nanoparticles. An international research . Inquire Now; Green synthesis of metals and their oxide nanoparticles
The formation of gold nanoparticles within live alfalfa plants will be discussed later in detail within the case study part of this book chapter. However it was also shown that silver nanoparticles could be formed within or uptaken by living alfalfa plants 29. Through a combination of uptake XAS and TEM studies it was shown that alfalfa .
Jul 01 2007 The first report of plants synthesizing gold or silver nanoparticles appeared when alfalfa seedlings were shown to uptake gold or silver from metals-enriched nutrient media 9 10. These studies demonstrated that AuIII or AgI ions were reduced in the solid media to Au0 or Ag0 by alfalfa plants and then the metal atoms were absorbed .
Aug 05 2014 Gardea et al. 40 41 investigated the formation and growth of Au and Ag nanoparticles inside live alfalfa plant. Although this method is considered to be a green synthesis method it is not usually applied to nanoparticle production because the synthesis of nanoparticles occurs in the biomass and their separation remains a big challenge.
