Abstract

Diatoms are incredibly diverse, photosynthetic microalgae, which are widely distributed in aquatic environments. The wide array and intricate morphology of the micro-and nanostructured silica exoskeletons encasing the single-celled diatoms offer a tremendous opportunity for biologically-assisted fabrication approaches. Herein, Coscinodiscus sp. diatom frustules were aligned on a silicon substrate and subsequently employed as shadow masks during the electron beam deposition of gold. This diatom frustule enabled stencil lithography approach yielded the capacity to precisely pattern gold structures on the silicon substrate with a large range of feature sizes, ranging down to the nanoscale.
