“…studied additional metal salts and observed very strong suppression of biomorph growth for Pb 2+ and Ag + ions . Moreover, organic additives such as amino acids and polymers have been introduced to typical biomorph solutions in attempts to further control silica precipitation . Inspired by biomineralization processes, other studies added proteins extracted from sea urchins and the spicules of marine sponges .…”

Also the counter ions (typically chloride) play a role in the crystallization dynamics.…”

A fundamental problem in chemistry is the nontrivial extension of molecular complexity to macroscopic length scales. The exploration of such concepts offers profound insights into the hierarchical organization of living matter and promises a novel engineering paradigm under which materials and devices are grown biomimetically far from the thermodynamic equilibrium. Inorganic microstructures called biomorphs are an ideal model system to develop such approaches. They are polycrystalline nanorod assemblies that form in basic solution from alkaline‐earth metal ions, silicate, and carbonate. Biomorphs range in size from tens of micrometers to millimeters and form over several hours under simple experimental settings. Their noneuhedral, life‐like shapes include surprising leafs, helices, funnels, urns, and coral‐shaped motifs. Here we review the current understanding of biomorphs, highlight links to nonlinear chemical dynamics, and discuss applications in materials science and astrobiology.

“…Morphology alone as a biosignature should be interpreted with caution as only organic metabolites spotted in fossils may be the unequivocal biomarkers of extinct life . Biogenicity models can be evaluated through the interaction of inorganic hosts with biomolecules such as proteins, or nucleic acids . Figure shows the structural changes induced by DNA and RNA on the formation of carbonate‐based silica biomorphs.…”

This Essay focuses briefly on early studies elaborated by natural and chemical philosophers,a nd the oncecalled synthetic biologists,w ho postulated the transition from inanimate to animate matter and even foresaw the possibility of creating artificial life on the basis of physical and chemical principles only.S uch ideas and speculations,r anging from soundness to weirdness,p aved however the way to current developments in areas like abiotic pattern formation, cell compartmentalization, biomineralization, or the origin of life itself.I np articular,t he generation of biomorphs and their relationship to microfossils represents an active research domain and seems to be the logical way to bring the historical work up to the future,a ss ome scientists are trying to make artificial cells.The last sections of this essay will also highlight modern science aimed at understanding what life is and, whether or not, it can be redefined in chemical terms.

Die Fluktuation des pH-Werts und die damit gekoppelte Präzipitation oszillieren, was zu einer wie in Abbildung 32 b gezeigten Verwindung führt.…”

Kristalle von verschiedenen Stoffen, z. B. von Elementen, Mineralien, einfachen Salzen, organischen Molekülkristallen und hochmolekularen Polymeren, können die Translationsfernordnung aufgeben, indem sie sich während des Wachstums verwinden und verbiegen. Diese Erscheinungen wurden bei Kristallen im Größenbereich von Nano‐ bis Zentimetern beobachtet. Wir analysieren, wie und warum viele Materialien solche oft drastischen nichtkristallographischen Verzerrungen wählen und betonen dabei die Kristallchemie, die zu Spannungen an Oberflächen von Kristalliten oder innerhalb des Volumens führt.
