Chitosan, carboxymethyl chitosan (CMCS) and chitosan sulfates (CSS) with different molecular weight were modified by reacting with 4-hydroxyl-5-chloride-1,3-benzene-disulfo-chloride or 2-hydroxyl-5-chloride-1,3-benzene-disulfo-chloride to give 12 kinds of new hydroxylbenzenesulfonailides derivatives of them.

The traditional motivation for integrating biological components into microfabricated devices has been to create biosensors that meld the molecular recognition capabilities of biology with the signal processing capabilities of electronic devices. However, a different motivation is emerging; biological components are being explored to radically change ...

Chitosan [a (1----4) 2-amino-2-deoxy-beta-D-Glucan] is a unique polysaccharide derived from chitin. Several attempts have been made to use this biopolymer in biomedical field. The use of this material in the development of hemodialysis membranes, artificial skin, drug targetting and other applications are discussed.

Chitosan and Thiolated Chitosan
2011Thiolated chitosans constitute an integral part of designated “thiomers”, which are thiolated polymers widely investigated for non-invasive drug delivery. In brief, thiomers display thiol-group-bearing ligands on their polymer backbone. Through thiol/disulfide exchange reactions and/or a simple oxidation process, disulfide bonds are formed between such

The derivatization of the primary amino groups of chitosan with coupling reagents bearing thiol functions leads to the formation of thiolated chitosans. So far, three types of thiolated chitosans have been generated: chitosan-cysteine conjugates, chitosan-thioglycolic acid conjugates and chitosan-4-thio-butyl-amidine conjugates.

Sintering of Chitosan and Chitosan Composites
Volume 3: Design, Materials and Manufacturing, Parts A, B, and C, 2012Chitosan is a naturally-occurring polymer that is derived through the deacetylation of chitin. Chitin, found in the exoskeletons of invertebrates, is ubiquitous in nature and easily collected as waste and repurposed for a multitude of industrial and biomedical applications.

AFM Studies of Chitosan, Gold‐Chitosan, and Silver‐Chitosan Films Morphology
Macromolecular Symposia, 2020AbstractAtomic force microscopy is used in this work as a primary tool for investigating chitosan‐based films morphology. Chitosan films casted from chitosan solutions in acetic acid of various concentrations, as well as gold‐ and silver‐containing chitosan films, are studied.

Application of chitosan and chitosan derivatives as biomaterials
Journal of Industrial and Engineering Chemistry, 2016Abstract Chitosan is a linear polysaccharide composed of randomly distributed β-(1-4)-linked d -glucosamine and N-acetyl- d -glucosamine. It is one of the major cationic polymers and the second most abundant polysaccharides in nature. It is extensively used to the biomedical and the industrial fields. Specially, chitosan has been studied much in the

Antimicrobial Properties of Chitosan and Chitosan Derivatives
2016The investigations of chitosan as an antimicrobial substance came into focus in the 1990s. The number of publications on this topic has been rapidly increasing since then, with more than 2,500 papers published in 2020. Initially, the interest was mainly related to potential applications in agriculture and food products, but currently, the emphasis on ...
