Macroporous gold has been prepared by impregnating artificial opals using electrodeposition. Both latex and silica spheres were used to prepare the opal templates. The silica spheres could be removed without damage to the patterned gold, which is subsequently an excellent reflection of the original template. The Figure shows a crystal of air spheres in gold prepared using silica spheres (see also inside front cover).
