Abstract: The practice of phytoremediation to remove unwanted elements from soils can be turned to a different application – to generate nanoparticles of a wanted element. The same processes are at work but the goal is different. In phytoremediation the task is to remove a contaminant from soil, whereas in phytomining it is to concentrate a valuable element and for phytosynthesis it is to synthesise a particular form, for example nanoparticles. The understanding of the formation of nanoparticles (generally noble metals) by plants also contributes to the understanding of the uptake and accumulation of specific elements by plants, which may then be applied to phytoremediation and to phytomining. This chapter describes the use of plants to produce silver nanoparticles and the understanding that has been developed around the mechanism underlying the nanoparticle formation.
