when travelling waves patterns are employed [108]. For example, the smooth flagellum of sperm [109] and the tinsel-like flagellum of goldenalgae Ochromonas[12] beat in the same pattern, featuring waves travelling away from the cell body. In Ochromonas, this results in a swimming direction towards the

, Germany 10.3762/bjnano.5.65 Abstract Chrysophyceae, also known as goldenalgae, contain characteristic, three-dimensional biomineralized silica structures. Their chemical composition and microscopic structure was studied. By high-temperature conversion of the skeleton of Mallomonas caudata and Synura
petersenii into elementary silicon by magnesium vapour, nanostructured defined replicates were produced which were clearly seen after removal of the formed magnesium oxide with acid.

In nature, there are
magnesium oxide occurs onto the diatoms [9]. Shen et al. have demonstrated the chemical transformation of diatoms into silicon by magnesium [17].
The chrysophytes sensu lato, also commonly referred to as goldenalgae because of the yellowish colour of their chloroplast, belong to the Stramenopiles [18
