| 1. A method of forming a structured surface on a substrate comprising:
exposing the substrate to an aqueous medium comprising living diatoms for a period of time sufficient to allow the living
diatoms to grow on the surface of the substrate; and
firing the substrate to burn out organic material within the diatoms and form the structured surface, wherein the structure
surface comprises a layer of siliceous diatomaceous frustules disposed on the substrate.
