Manufacture of Hollow Metal Nanostructures
Principal Investigator: Younan Xia
Nanostructures with hollow interiors offer several advantages over their solid counterparts in terms of weight, use of materials, and cost. Current methods of synthesizing hollow nanostructures of gold using colloidal templates have resulted in low yields, and the resulting gold nanoshells have rough surfaces, are polycrystalline, and are non-uniform in shell thickness and defined composition.
Our researchers have developed a new method to synthesize large amounts of well defined void sizes that are homogeneous and smooth. The finished products are highly crystalline walled nanostructures.
Some possible applications for hollow nanostructures are: 1) as ultra-light fillers for the new generation of electrically and thermally conductive composite materials, or 2) in fabrication of plasmonic devices, which are highly sensitive biosensors. Gold nanoshells can be used as probes, photothermal triggers for drug release, or as contrast agents. Palladium nanotubes could be used as recoverable catalysts and as a hydrogen storage medium.
