Multistrata Nanoparticles: The Multistrata Nanoparticle: an FeOx/Au Core/Shell Enveloped in a Silica–Au Shell (Small 9/2011)



original image

The frontispiece features the multistrata nanoparticle—a single-core, five-layered nanostructure. It combines tunable, dual-peak, UV–vis–NIR spectrum extinction characteristics; trimodal imaging contrast; a simple synthesis; and facile surface modification capabilities into a single <60-nm-diameter, multifunctional nanosphere that seeks to relieve current methodological limitations by coupling diagnostics and therapeutics into one single theranostic tool. The image shows a model of the interior, multilayered, metallodielectric structure, including a schematic of the fabrication protocol.
