Sentences with phrase «shell nanorods»

Nanorod structures aren't new, but the technique used by Lin's lab produces nanorods of uniform sizes — such as barium titanate and iron oxide, which have not yet been demonstrated via wet - chemistry approaches in the literature — and highly - uniform core - shell nanorods made by combining two dissimilar materials.

The gold - iron oxide core - shell nanorods may be useful in cancer therapy, with MRI imaging enabled by the iron oxide shell, and local heating created by the photothermal effect on the gold nanorod core killing cancer cells.

Not exact matches

«Once in solution, the TEOS begins to form a silica shell on the nanorods.

With thin shells, the change in size of the nanorods is minimal, and the gold nanorods can still pack into dense assemblies.

One way to help gold nanorods retain their shape during photothermal heating is to coat them with silica shells, which confine the nanorods to their original shape but allow light to pass through.

Gold nanorods are being investigated for use in a wide variety of biomedical applications, and this advance paves the way for more stable gold nanorods and for chemically functionalizing the surface of the shells.

«The silica shells offer multiple benefits — and our modified approach to coating gold nanorods with silica shells has two distinct advantages,» Tracy says.

On the other hand, thicker shells can act as buffers, preventing nanorods from bunching closely together and shielding them from their environment.

For the future, Lin envisions more complex nanocrystals with multifunctional shells and additional shapes, including nanorods and so - called «Janus» nanoparticles that are composed of biphasic geometry of two dissimilar materials.
