Abstract
The present invention includes nanotubes or rods, methods and arrays using plasmonic-magnetic bifunctional nanotubes or rods comprising: one or more silica nanotubes or rods; one or more nanomagnets embedded in a portion of the silica nanotubes or rods; and plasmonic metal nanoparticles uniformly coating in or on at least a portion of the surface of the nanomagnets and the silica nanotubes surface-coated.
Claims10
A method of making a plasmonic-magnetic nanocapsule comprising:
- a) forming a silica nanotube comprising a magnetic material embedded within the silica nanotube, wherein the magnetic material comprises a segmented metallic rod, wherein the segmented rod comprises segments of silver or gold, and segments of nickel;
- b) layering at least a portion of the outer surface of the silica nanotube with metallic nanoparticles;
- to provide a plasmonic-magnetic nanocapsule.
