Claim:
1. A method for the synthesis of metal nanoparticles containing an extract of Terfeziaceae comprising the steps of: a) adding about 5 g of Terfeziaceae (desert truffles) fruiting bodies to about 50 ml of water to form an aqueous Terfeziaceae mixture, and boiling the aqueous Terfeziaceae mixture for about 1-5 minutes to obtain a Terfeziaceae extract; b) dissolving about 1-5 mmol/ml silver nitrate (AgNO c) forming said silver nanoparticles by adding about 5 ml of the Terfeziaceae extract to the silver nitrate solution, resulting in a color change of the solution from colorless to dark brown due to a reduction of silver ions in the solution.
