Salmon milt DNA as a template for the mass production of Ag nanoparticles

A wet-chemical approach using DNA extracted from salmon milt as a template to mass produce Ag nanoparticles was developed. Spherical Ag nanoparticles with a main diameter of less than 10 nm were obtained. The concentration of Ag nanoparticles in the as-produced colloidal suspension was as high as 5....

Description
Summary:A wet-chemical approach using DNA extracted from salmon milt as a template to mass produce Ag nanoparticles was developed. Spherical Ag nanoparticles with a main diameter of less than 10 nm were obtained. The concentration of Ag nanoparticles in the as-produced colloidal suspension was as high as 5.3 × 10 −2  mol l −1 . This simple and effective procedure should offer an alternative route to the mass production of Ag nanoparticles for practical applications.
