Plants with the Midas Touch: Formation of Gold .

Jul 31, 2002 · In the well-known Greek legend the touch of King Midas would convert anything to metallic gold. 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 (1).

In 2002, Gardea-Torresdey led a team from UTEP and Mexico using technology at the Stanford Synchrotron Radiation Lightsource (SSRL) to study phytoremediation in alfalfa plants. The team demonstrated that alfalfa would extract gold from the medium in which it was growing and that it would store the gold in the form of nanoparticles.
