Abstract
The present invention involves growing diatoms on a surface for the purpose of forming nanoscale-sized siliceous structures on the surface. In accordance with the invention, diatom films are grown on various substrates, which are then fired to remove all organic material from the diatoms and produce a surface coated with intricate, nanoscale-sized structures. The nanoscale-sized structured surface is subsequently treated with a hydrophobic film-forming agent to form a structured self-cleaning surface.
