An exemplary embodiment of the invention is a method for making silver nanoparticles, and includes steps of reacting a silver salt with a phosphene amino acid to make silver nanoparticles. Exemplary phosphene amino acids include trimers, with a particular example being a trimeric amino acid conjugate containing one phosphene group. In an exemplary method of the invention, the silver nanoparticles may be produced in timer periods of less than about 30 minutes, and at temperatures of less than about 40&#xb0; C. Other methods of the invention are directed to methods for stabilizing silver nanoparticles.

Methods for producing silver nanoparticles

The invention provides stabilized, biocompatible gold nanoparticles that are stabilized with material from soy or lentil plant material or a reactive extract thereof of the plant material. The gold nanoparticles of the invention can be fabricated with an environmentally friendly method for making biocompatible stabilized gold nanoparticles. In methods of the invention, an aqueous solution containing gold salts is mixed with soy or lentil plant material or a reactive extract thereof. In preferred embodiment methods of making, an aqueous solution containing gold salts is provided. The aqueous solution is mixed with soy or lentil plant material or a reactive extract thereof. The gold salts react to form biocompatible gold nanoparticles that are stabilized with a robust coating derived of the soy or lentil plant material or a reactive extract thereof.
