TOOTH ENAMEL. “HAP is another biomineral, which was recently reported to form mesocrystals in tooth enamel-like structures and dentin remineralization suggesting a role of mesocrystals in calcium phosphate biominerals too.” https://lnkd.in/eNACsghr View in LinkedIn

EMERGENT PROPERTIES. “Mesocrystals from functional materials are highly attractive due to the emergent properties of mesocrystalline materials, such as single crystal-like behavior, high crystallinity, high porosity and inner connection bridged by organic components and/or inorganic nanocrystals. Such property combinations in a single material are unrivalled compared to amorphous, polycrystalline, and single-crystalline materials.” https://lnkd.in/eNACsghr View in LinkedIn

STRIKING ANALOGIES. “It is remarkable that the structural levels found for biopolymers such as proteins or polysaccharides have similar features as the structural levels found in a mesocrystal. Both structures rely on self organization/structuration processes in a solvent and it is useful to consider analogies.” https://lnkd.in/eNACsghr View in LinkedIn

SITEMAP. “An important lesson from the multilevel structure formation in biopolymers is the coding of the structural organization process by chemical functionalities, which is for example the amino acid sequence in proteins.” https://lnkd.in/eNACsghr View in LinkedIn

THE CORRESPONDENCE. “The smallest regular unit in such a crystal is the unit cell, which corresponds to the secondary structure in biopolymers (a-helix, B-sheet, y-turn). The interaction between several secondary structural elements of biopolymers defines the tertiary structure.” https://lnkd.in/eNACsghr View in LinkedIn

LEGO BLOCKS. “In analogy, a number of unit cells build the nanocrystal with potentially unusual shape and interaction pattern, which is the primary building unit in a nonclassical crystallization process.” https://lnkd.in/eNACsghr View in LinkedIn

LEVELS OF STRUCTURE. “Finally, the interaction between several tertiary units of a biopolymer forms the quaternary structure, for instance the fibrils in the collagen example in Figure 15. The analogy in the nonclassical crystallization scenario is the mesocrystal. with an either self-determined morphology (this is the usual case) or a morphology determined by an external template, which is likely the case for some biominerals.” https://lnkd.in/eNACsghr View in LinkedIn

BIOMIMICRY. “In addition, the close similarity between the structural cascades from primary to quaternary structures can explain the "bio-Iike" appearance and morphologies of many crystals formed by a nonclassical crystallization pathway. The formation of biopolymer quaternary structures from several different molecules (e.g., the insulin tertiary structure is formed from chain A and B) implies that it should also be possible to form mesocrystals that consist of chemically different nanocrystals.” https://lnkd.in/eNACsghr View in LinkedIn
