Abstract: Nanocages are formed by etching nanocubes. The nanocubes are added to an aqueous system having an amphiphilic lipid dissolved in an organic solvent (e.g. a hydrophobic alcohol) to form reverse micelles. As the water evaporates the micelles shrink as etching of the flat surface of the nanocubes occurs. In this fashion hollow nanocages are produced. In one embodiment, the nanocage is covalently attached to a polymer shell (e.g. a dextran shell).
