Widespread concerns over the impact of human activity on environment have resulted in a desire to replace artificial functional materials with naturally derived alternatives. As such, polysaccharides are drawing increasing attention due offering renewable, biodegradable, and biocompatible feedstock for nanomaterials. In particular, nanocrystals cellulose chitin emerged as versatile sustainable building blocks diverse applications, ranging from mechanical reinforcement structural coloration. Much this interest arises tendency these colloidally stable nanoparticles self-organize water into lyotropic cholesteric liquid crystal, which can be readily manipulated terms its periodicity, structure, geometry. Importantly, helicoidal ordering retained solid-state, an accessible route complex nanostructured films, coatings, particles. review, process forming iridescent, structurally colored films suspensions (CNCs) is summarized mechanisms underlying chemical physical phenomena at each stage explored. Analogy then drawn (ChNCs), allowing key differences critically assessed strategies toward coloration presented. progress translating technology academia industry summarized, unresolved scientific technical questions put forward challenges community.

Chitin, Chitosan, and Nanochitin: Extraction, Synthesis, and Applications

Polymers, Год журнала: 2022, Номер 14(19), С. 3989 - 3989

Опубликована: Сен. 23, 2022

Crustacean shells are a sustainable source of chitin. Extracting chitin from crustacean is ongoing research, much which devoted to devising process that yields high-quality with minimal waste. Chemical and biological methods have been used extensively for this purpose; more recently, based on ionic liquids deep eutectic solvents explored. Extracted can be converted into chitosan or nanochitin. Once obtained modified the desired form, it in wide array applications, including as filler material, adsorbents, component biomaterials, among others. Describing extraction chitin, synthesis nanochitin, applications these materials aim review. The first section review summarizes compares common methods, highlighting benefits shortcomings each, followed by descriptions convert second discusses some range its derivatives.

Chitosan-based nanostructured biomaterials: Synthesis, properties, and biomedical applications

Advanced Industrial and Engineering Polymer Research, Год журнала: 2023, Номер 7(1), С. 79 - 99

Опубликована: Июль 19, 2023

Chitosan is obtained from chitin, which abundantly found in crustaceans and through various methods. The demineralization, deproteinization, discoloration, deacetylation of chitin produce chitosan consisting D-glucosamine N-acetyl units that are linked β-(1,4)-glycosidic linkages. has gained significant attention the biomedical field due to its unique properties such as abundance, renewability, non-toxic nature, antimicrobial activity, biodegradability, polyfunctionality. One key why it been heavily utilized field. To provide a comprehensive overview chitosan, this review discusses extraction based on source It also delves into chemical modifications nanocomposite development using natural synthetic materials. emphasizes multitude make an excellent choice for wide range applications. mechanisms antibacterial activity factors affecting activity. Additionally, highlights hemocompatibility, antioxidant anti-inflammation, other contribute suitability different applications, including wound dressing materials, drug delivery carriers, biosensing diagnostic devices, bone substitutes, bioimaging. While discussing some limitations concludes with future perspective developing multifunctional chitosan-based nanomaterials could potentially move laboratory clinical trials treating diseases.

Refractory skin defects such as pressure ulcers, diabetic and vascular ulcers represent a challenge for clinicians researchers in many aspects. The treatment strategies wound healing have high cost limited efficacy. To ease the financial psychological burden on patients, more effective therapeutic approach is needed to address chronic wound. MSC-derived exosomes (MSC-exosomes), main bioactive extracellular vesicles of paracrine effect MSCs, been proposed new potential cell-free regeneration. benefits MSC-exosomes include their ability promote angiogenesis cell proliferation, increase collagen production, regulate inflammation, finally improve tissue regenerative capacity. However, poor targeting easy removability from are major obstacles use clinical therapy.
