Near-infrared light (650–900 nm) is of particular interest in biological applications as it is minimally absorbed by biological chromophores and water.

(b) Image showing the color range of HGN solutions. The vial on the far left contains solid gold nanoparticles, the rest are HNGs with varying diameters and wall thicknesses.

Calcein AM staining indicated that cancerous cells remained viable (evidenced by green fluorescent signal) when exposed to 1 mW laser power, regardless of nanoparticle presence. At 50 mW laser output a red fluorescent EthD-1 signal indicative of membrane damage was observed in cells exposed to anti-HER2 functionalized GGS NPs only where the laser was applied. Laser exposure alone was harmless to cells, as was laser exposure combined with nonspecifically targeted nanoparticles. Scale bar = 250 lm. Reprinted with permission from Day et al. Figure 4. Kaplan–Meier survival of mice following treatment with GGS NPs and laser irradiation. There is a statistically significant increase in survival with 48 h accumulation compared to 24 h accumulation for the GGS NP treated mice and no difference for 48 h GGS NP treated mice as compared to gold silica nanoshell treated mice.

(a) The extinction (Cext), absorption (Cabs), and scattering (Csca) cross-sections (note that Cext = Cabs + Csca) calculated using the DDA method for a gold nanocage of 45 nm in edge length and 3.5 nm in wall thickness, and with the geometry depicted in the inset in (d). The alloy composition of the nanocages is Au3Ag. (b) SEM images of Ag nanocubes prepared by sulfide-mediated polyol synthesis. The inset shows TEM image of the Ag nanocubes. (c) Normalized Vis–NIR extinction spectra recorded from aqueous suspensions of nanostructures after titrating Ag nanocubes with different amounts of a HAuCl4 aqueous solution. Note that the spectrum in red is corresponding to the Au nanocages shown in (d). (d) SEM image of Au nanocages prepared by refluxing an aqueous solution containing both silver nanocubes and HAuCl4. The inset shows a TEM image of the Au nanocages. Reprinted with permission from Chen et al. Copyright 2007 American Chemical Society. Figure 6. SK-BR-3 breast cancer cells that were treated with immuno gold nanocages and then irradiated by 810-nm laser at a power density of 1.5 W/cm for 5 min showed a well-defined circular zone of dead cells as revealed by: (a) calcein AM assay (where green fluorescence indicates the cells were live), and (b) EthD-1 assay (where red fluorescence indicates the cells were dead). In the control experiment, cells irradiated under the same conditions but without immuno gold nanocage treatment maintained viability, as indicated by (c) calcein fluorescence assay, and (d) the lack of intracellular EthD-1 uptake.

(a) Photograph of a tumor-bearing mouse under the photothermal treatment. 100 lL of PEGylated nanocages at a concentration of 9 9 10 particles/mL or saline was administrated intravenously through the tail vein as indicated by an arrow. After the nanocages had been cleared from the circulation (72 h after injection), the tumor on the right frank was irradiated by the diode laser at 0.7 W/cm with a beam Address correspondence to Rebekah A.
