These gold nanoshells are shuttled into tumors by the use of phagocytosis, where phagocytes engulf the nanoshells through the cell membrane to form an internal phagosome, or macrophage. After this it is shuttled into a cell and enzymes are usually used to metabolize it and shuttle it back out of the cell.
Gold nanoparticle technology shows promise in the advancement of cancer treatments. Some of the properties that gold nanoparticles possess, such as small size, non-toxicity and non-immunogenicity make these molecules useful candidates for targeted drug delivery systems.
Gold nanoshells, coated silica nanoparticles with a thin layer of gold. [6] have been conjugated to antibodies (anti-HER2 or anti-IgG) via PEG linkers. After incubation of SKBr3 cancer cells with the gold nanoshells, an 820 nm laser was used to irradiate the cells. Only the cells incubated with the gold nanoshells conjugated with the specific ...

Halas' work in the 21st century focuses on noble metal nanoshells covering semiconducting or insulating cores. Her research was the first to experimentally show that nanoshells with different dimensions and shapes have different plasmonic resonances, and that these resonances could therefore be tuned by changing nanoparticle geometries.
