Metal@Polymer Nanoparticles by Simultaneous Precipitation and Reduction

Description:

Metal@Polymer Nanoparticles by Simultaneous Precipitation

and Reduction

Princeton Docket #14-3014

 

 

Researchers in the Department of Chemical and Biological Engineering at Princeton University have developed a simple one-step synergistic preparation of metal nanoparticles within spherical polymer nanoparticles through Flash NanoPrecipitation(FNP). Polystyrene-block-poly(vinylpyridine) (PS-b-PVP) in THF, aqueous metal ion salts, and reducing agent solutions are employed as polymer stream, non-solvent stream and collection solution, respectively. Uniform metal nanoparticles grown on polymer nanospheres are obtained through the one-step FNP process. The particle size and metal nanoparticle loading amount can be tuned by changing the preparation parameters. These nanoparticles have potential applications in the fields of catalysis, adsorbents, drug delivery, biodiagnostics and as a single nanoreactor. Samples are available for examination.

Faculty Inventors

Rodney Priestley is Assistant Professor of Chemical and Biological Engineering at Princeton University. His research interest is in the physics of polymeric materials and the development of novel polymeric systems as responsive and self-healing materials and membranes. Professor Priestley has won the Air Force Young Investigator Award (2012), NSF Career Award (2011), 3M-Nontenured Faculty Grant (2010), ACS Young Investigator Award (2009) and International Quadrant Award (2009).

 

Robert K Prud’homme is Professor of Chemical and Biological Engineering, Department of Chemical and Biological Engineering and the Director, Program in Engineering Biology, at Princeton University. His research focuses on how weak forces at the molecular level determine macroscopic properties at larger length scales. Equal time is spent on understanding the details of molecular-level interactions using NMR, neutron scattering, x-ray scattering, or electron microscopy and making measurements of bulk properties such as rheology, diffusion of proteins in gels, drop sizes of sprays, or pressure drop measurements in porous media. A major focus of his lab’s research is on using self-assembly to construct nanoparticles for drug delivery and imaging. The work is highly interdisciplinary; many of the projects involve joint advisors and collaborations with researchers at NIH, Argonne National Labs, CNRS in France, or major corporate research.
