Tunable Hollow Metal Nanorods- A Novel Approach

An adaptable approach for preparing nano-materials of engineered size, shape, composition, and porosity has been developed by researchers at Simon Fraser University, Canada.
They have developed a simple technique to engineer hollow metal nanostructures of well-defined properties.
The nanostructures have a tunable diameter, length, and shape that are defined by the sacrificial template used to grow the hollow product. The electrochemically synthesized templates are
regular, polycrystalline cylindrical silver nanorods with dimensions dictated by both the physical mold that confines their growth as well as the conditions for electrodeposition. This template can be selectively etched to isolate a porous hollow nanostructure.
These robust hollow metal nanostructures have potential applications in the selective delivery and release of reagents such as medicinal drugs.
The photothermal properties of metal nanostructures have been investigated for destroying cancer cells.
