Soybean protein: A natural source for the production of green silver nanoparticles

Abstract

The ethnopharmacological approach to the production of nanoparticles is directly related to the creation of an important symbiosis between nanoscience and medical science. Production of nanoparticles under ecofriendly conditions is of significance to address growing concerns on the overall toxicity of nanoparticles for medical and biotechnological applications. The present investigation demonstrates silver nanoparticles production capabilities of a miracle bean soybean Glycine max. We found that a single protein of soybean with a molecular weight of 51 kDa stabilizes the newly formed silver nanoparticles. The electroeluted protein has confirmed the bioreduction property of silver ions. © The Korean Society for Biotechnology and Bioengineering and Springer 2012.
