There is significant interest in titanium oxide and germanium-silicon oxide nanocomposites for optoelectronic, photocatalytic, and solar cell applications. The ability of the marine diatom Pinnularia sp. to uptake solub ...

Marine diatoms are a class of microalgae that possess cell walls composed of silica nanoparticles. These organisms actively assimilate silicic acid Si(OH)4 from seawater, polymerize silicic acid to silica nanoparticles ...

Nature is an inspirational source of silica structures that possess unique optical properties. A few classes of organisms fabricate metal oxides with nanoscale features by a bottom-up self assembly process. In particula ...
