Poly(NIPAAm-co-AAm)-gold nanoshell composites for optically-triggered cancer therapeutic delivery
… (NIPAAm-co-AAm) hydrogel and gold-silica nanoshells. Thermally responsive hydrogels undergo a physical property transition at their lower critical solution temperature (LCST). When transitioning from below to above the LCST, the hydrogel material expels large amounts of water and absorbed …

Gold Nanoshells: Synthesis and Applications to In Situ SERS
… were synthesized and then assembled to form a nanoshell array/glassy carbon electrode for in situ SERS. Some fundamental issues critical to understanding the nanoshell synthesis mechanism were also addressed. By using the new SERS electrode, the interfacial adsorption structure of Nafion on Pt …

Gold nanoshells for surface enhanced Raman spectroscopy and drug delivery
Gold nanoshells are tunable plasmonic nanostructures consisting of spherical silica cores wrapped with thin layer of Au. Based on the size of the Au layer with respect to the silica core, gold nanoshells can resonantly absorb or scatter light at any wavelength on the visible or infrared. On …

Spatially-resolved reflectance spectroscopy with variable fiber geometry
… angled fiber geometry may be coupled with gold nanoshells to provide significantly enhanced scattering contrast when nanoshells are selectively conjugated with dysplastic epithelial tissue. An equal magnitude of scattering contrast can be induced with markedly less gold nanoshell dosage when the …
