Chitin and chitosan: Properties and applications

TL;DR: This review presents chemical modifications of chitosan via using photosensitizers, dendrimers, sugars, cyclodextrins and crown ethers as modifiers and places an emphasis on the applications of ch itosan derivatives as carriers in drug delivery systems, as supporting materials for tissue engineering, as dye removing agents and as metal ion adsorbents.

TL;DR: A comprehensive review on physicochemical, structural and functional characteristics (e.g., emulsifying properties) of the Persian gum is provided in this article, with the view of using it for improving the flow behavior, texture or shelf life stability of food products.

TL;DR: A review of biomaterials derived from and inspired by natural proteins and polysaccharides and highlights their promise across diverse biomedical fields can be found in this paper, where the authors outline current therapeutic applications of these nature-based materials and consider expected future developments in identifying and utilising innovative biommaterials in new biomedical applications.

TL;DR: In this paper , the authors summarized the latest research on the development, properties and applications of natural polysaccharide-based intelligent food packaging materials and showed that poly-saccharides have a good application prospect in the intelligent packaging industry.

TL;DR: A review of the literature on enzymes immobilized on chitin- and chitosan-based materials, covering the last decade, is presented in this paper, where one hundred fifty-eight papers on 63 immobilized enzymes for multiplicity of applications ranging from wine, sugar and fish industry, through organic compounds removal from wastewaters to sophisticated biosensors for both in situ measurements of environmental pollutants and metabolite control in artificial organs, are reviewed.

TL;DR: This study reports for the first time the use of polymer/polyol salt aqueous solutions as gelling systems, suggesting the discovery of a prototype for a new family of thermosetting gels highly compatible with biological compounds.

TL;DR: The use of infrared spectroscopy for characterization of the composition of chitin and chitosan covering the entire range of degree of acetylation (DA) and a wide variety of raw materials is examined further in this article.
