Plant extracts from live alfalfa, the broths of lemongrass, geranium leaves and others have served as green reactants in Ag NP synthesis (Torresdey et al., 2003, Shankar et al., 2003b, Shankar et al., 2005). The reaction of aqueous AgNO 3 with an aqueous extract of leaves of a common ornamental geranium plant, P. graveolens, gave Ag NPs after 24 h.
"In this case, alfalfa was chosen as a model plant system for studying the ability of plants to extract gold from various growth media." AFAIK alfalfa is a fastgrowing and quite easy plant, so it makes sense to use it as a model plant.

Alfalfa is one of Okloma''s most important crops, occupying about 400,000 acres and generating 100200 million in direct sales. Higher monetary values are cited when the "valueadded" aspects of animal products are included. The yield of alfalfa and stand life depend on many management decisions.
Scientists use alfalfa plants to harvest nanoparticles of gold. ... Phytomining of gold involves extracting gold from soil substrates by harvesting specially selected hyperaccumulating plants. Phytomining has potential to allow economic exploitation of low grade ores or mineralized soils that are too poor for conventional mining of metals.

Jul 10, 2013· We have synthesized silver nanoparticles from silver nitrate solutions using extracts of Rumex hymenosepalus, a plant widely found in a large region in North America, as reducing agent. This plant is known to be rich in antioxidant molecules which we use as reducing agents. Silver nanoparticles grow in a singlestep method, at room temperature, and with no addition of external energy.
plant species, Canola and Alfalfa on picking up gold and formation of its nanoparticles. Seeds of varieties of Canola and Alfalfa plant species selected for investigation are listed in Table 1. The seeds were washed with sterile water in an effort to remove any pathogenic contamination on them. They
resources from soil. Phytomining is the use of live plants to recover valuable metals from waste mining substrates (tailings) or mineralized soils. Phytomining has been applied to areas where the metal concentration is not suitable for viable extraction using conventional technologies (Anderson et al. 1998). In
