Journal ArticleDOI
Polycationic Peptides from Diatom Biosilica That Direct Silica Nanosphere Formation
TL;DR: A set of polycationic peptides isolated from diatom cell walls were shown to generate networks of silica nanospheres within seconds when added to a solution of silicic acid.
Journal ArticleDOI
Self-Assembly of Highly Phosphorylated Silaffins and Their Function in Biosilica Morphogenesis
TL;DR: Time-resolved analysis of silica morphogenesis in vitro detected a plastic silaffin-silica phase, which may represent a building material for diatom biosilica.
Journal ArticleDOI
Species-specific polyamines from diatoms control silica morphology
TL;DR: The chemical structure of long-chain polyamines (up to 20 repeated units), which represent the main organic constituent of diatom biosilica, are described, which are the longest polyamine chains found in nature and induce rapid silica precipitation from a silicic acid solution.
Journal ArticleDOI
Silica formation in diatoms: the function of long-chain polyamines and silaffins
Manfred Sumper,Nils Kröger +1 more
TL;DR: In recent years, insight into the molecules and mechanism that allow diatoms to perform silica morphogenesis under ambient conditions has been gained as mentioned in this paper, which is among the most remarkable examples of biological nanofabrication.
Journal ArticleDOI
Learning from Diatoms: Nature's Tools for the Production of Nanostructured Silica
Manfred Sumper,Eike Brunner +1 more
TL;DR: In this article, it was shown that diatom biosilica is a composite material containing zwitterionic proteins (silaffins) and long-chain polyamines in addition to silica.
