Gold Nanoparticles by Alfalfa Plants

Recently, a team working at SSRL lead by Professor Jorge Gardea-Torresdey from the University of Texas at El Paso have shown that ordinary alfalfa plants can accumulate very small particles (nanoparticles) of metallic gold . The best-known materials that contain nanoparticles of metallic gold are gold colloids. These lack the familiar metallic luster, but show bright colors which range from red,

Gold nanoparticles from plants — Science Learning Hub

A few years ago, scientists in New Zealand helped develop a process called phytomining. Plants are grown on gold-rich soil, such as waste from mines. They take up the gold and store it as nanoparticles throughout their tissues. The plants are harvested, and the gold is recovered and accumulated into ‘normal’ gold. Phytomining can also be used to recover other metals.
