Biomimicry yields nanomaterials: For electronics, radar deflection, and solar cells:  "Daniel Morse of the University of California, Santa Barbara, said he has harnessed the ability of the lowly sponge to develop silicon-based, photovoltaic devices. The organisms "fabricate beautifully structured, 3-dimensionally organized high performance materials," he said. They accomplish this under benign conditions -- unlike those used in the human fabrication of silicon chips, which can involve high temperatures and pressures and polluting materials. Morse and colleagues discovered a class of proteins, which he nicknamed "silicateins," that direct the manipulation of silica in sponges found in the waters just outside his California lab. He said he discovered silacatein enzymes can act as nanomachines to make titanium dioxide by aligning titanium and oxygen atoms, thereby turning the material into "one of the most efficient photovoltaic converters of sunlight to electricity yet known."
