Highly porous gold beads have been synthesized from gold nanoparticle “building blocks” using emulsion- templated polymer beads as scaffolds (see Figure and cover for scanning electron microscopy images). The distribution of the nanoparticles throughout the scaffold can be controlled, which in turn allows a variety of complex structures to be produced.
