Cholesteric liquid crystals in living matter

Cholesteric liquid crystals are omnipresent in living matter under both in vivo and in vitro conditions and address the major types of molecules essential to life. In the animal and plant kingdoms, the cholesteric structure is a recurring design, suggesting a convergent evolution to an optimised left-handed helix.

Physics of liquid crystals in cell biology

2021-6-6 · Box 1. Primer on liquid crystals Liquid crystals are an intermediate phase of matter between solids and liquids. In a solid constituent atoms organise in well-structured crystalline lattices, giving them a high degree of positional and orientational ordering. In a liquid, both po-sitional and orientational ordering are absent. As an ...

What Are Liquid Crystals? - Kent State University

2022-3-10 · Until two scientists in Europe, Friedrich Reinitzer and Otto Lehmann, discovered liquid crystals in the late 19th century, these three were the only states of matter that humans have ever known. Liquid crystal is the fourth state of matter that occurs between solid and liquid. While studying the function of cholesterol in plants, Friedrich ...

Liquid Crystals in Biological Systems: Molecular Crystals ...

2018-6-9 · There are several good theoretical reasons why matter in the liquid crystalline state should play a part in the structure of living tissue. Many naturally-occurring substances exhibit paracrystalline behavior. The most complex and some of the most reactive forms, the so-called cholesteric, are mainly or exclusively of natural origin.

Liquid Crystalline Collagen: A Self-Assembled Morphology ...

2009-2-10 · We report the creation of collagen films having a cholesteric banding structure with an orientation that can be systematically controlled. The action of hydrodynamic flow and rapid desiccation was used to influence the orientation of collagen fibrils, producing a film with a twisted plywood architecture. Adult human fibroblasts cultured on these substrates orient in the …

Crystals and Crystallization in Biological Systems ...

There are few instances of real crystals in living systems, although liquid crystalline structures exist in abundance. The formation of gall and kidney stones takes place because of metabolic distrubances. Blood clotting is a defense reaction, biochemically initiated. The crystalline lens is the prime example of an in vivo crystal structure.

Topological defects in active liquid crystals - IOPscience

2019-11-26 · Living liquid crystal (LLC) is a composite material represented by a suspension of microswimmers like bacteria in a nontoxic lyotropic liquid crystal [33, 54, 57, 73, 74]. The material is conceived by mixing a highly-structured synthetic liquid crystal with a small amount of 'active dopant' (i.e., bacteria).
