In this mini-review, we shall first cover a short history of the discovery chitin isolated from sponges; as well its evolutionarily ancient roots. Next, will delve into unique structural, mechanical, and thermal properties naturally occurring polymer to illuminate how physicochemical may find uses in diverse areas material sciences. We show morphology sponge renders it quite useful for new route “Extreme Biomimetics”; where high temperatures pressures allow range interesting bioinorganic...
Sponges are a valuable source of natural compounds and biomaterials for many biotechnological applications. Marine sponges belonging to the order Verongiida known contain both chitin biologically active bromotyrosines. Aplysina archeri (Aplysineidae: Verongiida) is well bromotyrosines with relevant bioactivity against human animal diseases. The aim this study was develop an express method production naturally prefabricated 3D bromotyrosine-containing extracts simultaneously. This new based...
The characteristic mineral-free fibrous skeletons (made of structural protein-spongin) <italic>H. communis</italic> (Demospongiae: Porifera) was used as a template in hydrothermal synthesis hematite (α-Fe<sub>2</sub>O<sub>3</sub>) nanoparticles.
We report a strategy for preserving the structural features of collagen triple helix in turbostratic graphite.
Abstract Modern scaffolding strategies include two key ways: to produce requested 3D constructs from corresponding precursors using technological tools, or simply use naturally already pre-fabricated scaffolds if they originate renewable sources. Marine sponges inhabit oceans since the Precambrian. These ancient multicellular organisms possess a broad variety of evolutionary approved and ready skeletal structures, which seem be well applicable as in diverse fields modern bioinspired...
Naturally occurring three-dimensional (3D) biopolymer-based matrices that can be used in different biomedical applications are sustainable alternatives to various artificial 3D materials. For this purpose, chitin-based structures from marine sponges very promising substitutes. Marine the order Verongiida (class Demospongiae) typical examples of demosponges with well-developed chitinous skeletons. In particular, species belonging family Ianthellidae possess chitinous, flat, fan-like fibrous...
Diatoms are considered unicellular eukaryotic organisms exclusively depositing biogenic silica. Heretofore there has been no report of calcification by these algae. Here it is shown that calcium carbonate within the stalks Didymosphenia geminata , a nuisance species prolifically colonized streams and rivers globally, in origin occurs as network calcite nanofibers. The nanofibrous framework mineralized polysaccharide matrix imparts mechanical support to stalks, providing stability variable...
Marine sponges remain representative of a unique source renewable biological materials. The demosponges the family Ianthellidae possess chitin-based skeletons with high biomimetic potential. These three-dimensional (3D) constructs can potentially be used in tissue engineering and regenerative medicine. In this study, we focus our attention, for first time, on marine sponge Ianthella labyrinthus Bergquist & Kelly-Borges, 1995 (Demospongiae: Verongida: Ianthellidae) as novel potential...
The bioactive bromotyrosine-derived alkaloids and unique morphologically-defined fibrous skeleton of chitin origin have been found recently in marine demosponges the order Verongiida. sophisticated three-dimensional (3D) structure skeletal chitinous scaffolds supported their use biomedicine, tissue engineering as well diverse modern technologies. goal this study was screening new species Verongiida to find another renewable source naturally prefabricated 3D scaffolds. Special attention paid...
Marine demosponges (Porifera: Demospongiae) are recognized as first metazoans which have developed over millions of years evolution effective survival strategies based on unique metabolic pathways to produce both biologically active secondary metabolites and biopolymer-based stiff skeletons with 3D architecture. Up date, among marine demosponges, only representatives the Verongiida order been known synthetize substances well made structural polysaccharide chitin. This work, our knowledge,...
Chitin, as a fundamental polysaccharide in invertebrate skeletons, continues to be actively investigated, especially with respect new sources and the development of effective methods for its extraction. Recent attention has been focused on marine crustaceans sponges; however, potential spiders (order Araneae) an alternative source tubular chitin overlooked. In this work, we our from up 12 cm-large Theraphosidae spiders, popularly known tarantulas or bird-eating spiders. These organisms...
Structure-based tissue engineering requires large-scale 3D cell/tissue manufacture technologies, to produce biologically active scaffolds. Special attention is currently paid naturally pre-designed scaffolds found in skeletons of marine sponges, which represent a renewable resource biomaterials. Here, an innovative approach the production mineralized natural origin proposed. For first time, method obtain calcium carbonate deposition ex vivo, using living mollusks hemolymph and...
The design of new composite materials using extreme biomimetics is crucial importance for bioinspired science. Further progress in research and application these impossible without understanding the mechanisms formation, as well structural features at molecular nano-level. It presents a challenge to obtain holistic underlying interaction organic inorganic phases under conditions harsh chemical reactions biopolymers. Yet, an can lead development unusual-but functional-hybrid materials. In...
Abstract Actin is a fundamental member of an ancient superfamily structural intracellular proteins and plays crucial role in cytoskeleton dynamics, ciliogenesis, phagocytosis, force generation both prokaryotes eukaryotes. It shown that actin has another function metazoans: patterning biosilica deposition, spanned over 500 million years.
