Abstract

Fungi make of piles of gold! A green-chemistry route, based on the bioreduction of AuCl4- ions by the fungus Verticillium sp., for the formation of gold nanoparticles is demonstrated. The TEM micrograph shows a single Verticillium cell after reaction with gold ions and entrapment of gold nano-particles on the cell wall and cytoplasmic membrane.
