Yolk-Shell Nanostructures via One-Step Core-Shell-Shell Template

Description:

Yolk-Shell Nanostructures via One-Step Core-Shell-Shell Template

Princeton Docket #14-2983

Yolk-shell nanoparticles are characterized by a movable core encapsulated inside a polymer or inorganic shell. At present, only a few ingenious routes for the generation of yolk-shell nanoparticles exist. These methods require cumbersome synthesis, multi-step procedures and/or lengthy process times. These processes are not scalable to produce commercial amounts of yolk-shell nanoparticles.

Researchers in the Department of Chemical and Biological Engineering at Princeton University have developed a rapid and facile route to prepare yolk-shell nanoparticles via one-step core-shell-shell template. It is anticipated that a range of yolk-shell nanoparticles can be prepared by one-step templating method. These nanoparticles have potential applications in the fields of catalysis, adsorbents, drug delivery, biodiagnostics and as a single nanoreactor. Samples are available for examination.

Applications:

· Single nanoreactors

· Catalyst support

· Catalyst for energy reactions

· Adsorbents

· Drug Delivery

· Medical imaging/biodiagnostics

Advantages:

· One-step process

· Low energy

· Short processing time

· Samples available for examination
