| Abstract: | Different varieties of two plant species,
Canola and Alfalfa were grown at exactly same laboratory conditions and
bio-reduction of Au (III) to Au (0) was studied. Subsequently, production of
gold nano-particles of various morphologies and sizes were characterized. Plant
seeds were grown in a culture medium that contained gold ions from KAuCl4.
Gold nano-particle formation was analyzed by atomic absorption spectrometry and
transmission electron microscopy. Results showed that the plants pull up gold
ions from KAuCl4 and form gold particles in nano sizes due to
chemical behaviour of the gold. Significant differences in the nature of
nano-particles were observed when particles synthesized by these two plant
species were compared. The size range of gold nano-particles synthesized by
Canola was 20-128 nm, while it was 8-48 nm by Alfalfa. |
