Diatoms are unicellular microscopic organisms with silicon dioxide-based cylindrical-shaped skeletons, enveloped with an organic material composed of essentially polysaccharides and proteins. By removing the organic compounds from the diatom, we present an alternative method for the preparation of insulating nanocapillaries. The lengths of the capillaries are about 100 μm and the diameters of the regularly structured pores are about 200 nm. Moreover, we confirm with measurements by XPS that the shell of the Pennales diatoms contains mostly SiO2.
