Chitin Research Revisited

Marine Drugs, 2010
Two centuries after the discovery of chitin, it is widely accepted that this biopolymer is an important biomaterial in many aspects. Numerous studies on chitin have focused on its biomedical applications.

Nanostructured biocomposite films of high toughness based on native chitin nanofibers and chitosan

Frontiers in Chemistry, 2014
Chitosan is widely used in films for packaging applications. Chitosan reinforcement by stiff particles or fibers is usually obtained at the expense of lowered ductility and toughness.

Chitin, Chitosan, and Its Derivatives for Wound Healing: Old and New Materials

Journal of Functional Biomaterials, 2015
Chitin (β-(1-4)-poly-N-acetyl-D-glucosamine) is widely distributed in nature and is the second most abundant polysaccharide after cellulose. It is often converted to its more deacetylated derivative, chitosan.

Polymer organogelation with chitin and chitin nanocrystals

RSC Advances, 2015
In this paper, we show that biodegradable and biocompatible organogels can be formed with chitin as the filler material and triglycerides as the continuous hydrophobic phase.

Structural and Material Properties of Chitin Nanofibers Produced Without Deacetylation Treatment

Nano Select
Deacetylation pretreatment is commonly applied to chitin nanofibers to introduce positive charges on their surface, increasing their fibrillation efficiency in water. However, without this treatment, chitin cannot be easily disintegrated into fibers with

Full-Length Transcriptome of Thalassiosira weissflogii as a Reference Resource and Mining of Chitin-Related Genes

Marine Drugs, 2021
β-Chitin produced by diatoms is expected to have significant economic and ecological value due to its structure, which consists of parallel chains of chitin, its properties and the high abundance of diatoms.

Genome-Wide Mining of Chitinase Diversity in the Marine Diatom Thalassiosira weissflogii and Functional Characterization of a Novel GH19 Enzyme

Marine Drugs
Chitin represents a globally abundant marine polymer with significant ecological and biotechnological value. β-chitin is an important carbon fixation product of diatoms and has a greater range of applications than α- and γ-chitin. However, there has been

Sustainable Production of Chitin from Supercritical CO₂ Defatted Domestic Cricket (Acheta domesticus L.) Meal: One-Pot Preparation, Characterization, and Effects of Different Deep Eutectic Solvents

Polysaccharides
Current resource and processing constraints on conventional chitin production call for novel sources and more sustainable methods for its production. Herein, domestic cricket (Acheta domesticus L.) meal obtained from supercritical CO2 oil extraction was ...

Chitin Hydrogels Prepared at Various Lithium Chloride/N,N-Dimethylacetamide Solutions by Water Vapor-Induced Phase Inversion

Journal of Chemistry, 2020
Chitin was chemically extracted from crab shells and then dissolved in N,N-dimethylacetamide (DMAc) solvent with lithium chloride (LiCl) at 3, 5, 7, and 10%. The concentrated chitin-DMAc/LiCl solutions were used for the preparation of chitin hydrogels by

Chitin modulates innate immune responses of keratinocytes. [PDF]

PLoS ONE, 2011
BACKGROUND: Chitin, after cellulose the second most abundant polysaccharide in nature, is an essential component of exoskeletons of crabs, shrimps and insects and protects these organisms from harsh conditions in their environment.
