Figure 8. . Gold nanocages as delivery vehicles for controlled drug release.
(A) A schematic illustration of controlled release enabled by a smart polymer, poly(N-isopropylacrylamide), coated on the surface of Au nanocages; (B) release profile of Dox from the system shown in (A), as triggered by a NIR laser [67]; (C) a schematic illustration of controlled release assisted by a phase-change materials (PCMs); and (D) release profiles of the dye from PCM-containing Au nanocages shown in (C) when exposed to HIFU [68].
