Fungus makes silica nanoparticles from sand

Abstract:
Bioleaching by organisms such as algae, mosses, lichens, bacteria and fungi has become a reasonably common technique for the commercial production of metals such as copper, iron and gold. Now, researchers at India’s National Chemical Laboratory have found that the fungus Fusarium oxysporum, which normally causes disease in plants, can create nanoparticles of silica from sand.

“This is commercially exciting,” said Murali Sastry. “It is green chemistry: no toxic chemicals are employed and the microbes aren't pathogenic to humans. Furthermore, nano-oxides are derived from a cheap source - sand - at room temperature.”
