Metal nanoparticles belong to the most fabricated nanomaterials because of their unique physical and chemical properties which can be used for analytical, biochemical and biotechnological applications. Biosynthesis of metal nanoparticles has been extensively studied since the present production of nanoparticles by chemical and physical methods is difficult in terms of the use of toxic chemicals and energy consumption. In plants, there is the largest accumulation of heavy metals in the ecosystem. Therefore plants have a great potential for the biosynthesis of nanoparticles. Influence of various external reaction´s conditions can affect appearance of produced nanoparticles. This fact opens unlimited possibilities for biosynthesis of novel nanoparticles that may vary in size, shape and surface modification..
