Abstract
This invention relates to cost-effective methods for synthesizing metallic nanoparticles in high yield using non-dendrimeric branched polymeric templates, such as branched polyethyleneimine. This invention also provides a high-throughput apparatus for synthesizing metallic nanoparticles under conditions that produce less waste than conventional nanoparticle synthesis methods. Also provided are metallic nanoparticles and multi-metallic nanoparticle compositions made by methods and high-throughput apparatus of the invention.
Claims15
A method of synthesizing metallic nanoparticles, the method comprising
- providing a first flow stream comprising an aqueous salt solution comprising ions of a transition metal and a branched polymeric template, wherein the branched polymeric template is not a dendrimer;
- providing a second flow stream comprising a reducing agent to reduce the ions of the transition metal to form metallic nanoparticles within the branched polymeric template;
- separating the metallic nanoparticles from the branched polymeric template using a purification method selected from the group consisting of a ligand exchange reaction, diafiltration, or oxygen plasma.
