Special Issue Information

Dear Colleagues,

Chitin as a polymer is one of the most abundant element of marine environment and comes after cellulose on Earth. Chitosan is a product of natural polysaccharide chitin to remove part of the acetyl group. It has many physiological functions such as biodegradability, biocompatibility, non-toxicity, anti-cancer, lipid-lowering, immunity enhancement, etc. It is widely used in food additives, textiles, agriculture, environmental protection, beauty care, cosmetics, antibacterial agents, medical fibers, medical dressings, artificial tissue materials and other fields.  

It gives us immense pleasure to announce this Special Issue of ‘Chitin and Chitosan of Molecules: Versatile Ecological, Industrial, and Biomedical Applications’. The goal of this special issue is to provide a platform for scientists and academicians all over the world to promote, share, and discuss various new issues and developments in chemistry, environmental, biotechnology and biomedical aspects of chitin and chitosan
In this special issue, we intend to invite front-line researchers and authors to submit original research and review articles on exploring Chitin and Chitosan, relevance of chitosan-based formulations and composites in the design and fabrication of medical devices, drug delivery systems, food packaging, and water purification systems.

Potential topics include but are not limited to the following:

  • New Methods in Chitin, Chitosan and Oligosaccharides Production
  • Advances in Organic Chemistry of Chitin and Chitosan
  • Advances in Physical Chemistry of Chitin and Chitosan
  • Chitin and Chitosan interactions with other molecular species
  • Chitosan-based nanocomposite for drug delivery
  • Chitosan-based material for gene delivery.
  • Chitosan/chitin-carbonaceous material composites for the adsorption of water pollutants
  • Chitosan-based systems for medical devices, and food packaging.
  • New and upcoming chitosan-based products and markets
  • Structure–property relationships in composites based on chitosan;
  • Chitosan-based systems for environmental applications.
  • Recent advancements in applications of chitosan-based biomaterials for skin tissue engineering.

Animal chitosan (Chit-A) is gaining more acceptance in daily activities. It is used in a range of products from food supplements for weight loss to even raw materials for producing nanoparticles and hydrogel drug carriers; however, it has low antioxidant activity. Fungal oligochitosan (OChit-F) was identified as a potential substitute for Chit-A. Cunninghamella elegans is a fungus found in the Brazilian savanna (Caatinga) that produces OligoChit-F, which is a relatively poorly studied compound. In this study, 4 kDa OChit-F with a 76% deacetylation degree was extracted from C. elegans. OChit-F showed antioxidant activity similar to that of Chit-A in only one in vitro test (copper chelation) but exhibited higher activity than that of Chit-A in three other tests (reducing power, hydroxyl radical scavenging, and iron chelation). These results indicate that OChit-F is a better antioxidant than Chit-A. In addition, Chit-A significantly increased the formation of calcium oxalate crystals in vitro, particularly those of the monohydrate (COM) type; however, OChit-F had no effect on this process in vitro. In summary, OChit-F had higher antioxidant activity than Chit-A and did not induce the formation of CaOx crystals. Thus, OChit-F can be used as a Chit-A substitute in applications affected by oxidative stress. Full article
