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

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.

Antifungal properties of Schiff bases of chitosan, N-substituted chitosan and quaternized chitosan
Carbohydrate Research, 2007Schiff bases of chitosan, N-substituted chitosan, and quaternized chitosan were synthesized and their antifungal properties were analyzed against Botrytis cinerea Pers. (B. cinerea pers.) and Colletotrichum lagenarium (Pass) Ell.et halst (C. lagenarium (Pass) Ell.et halst) based on the method of D. Jasso de Rodríguez and co-workers.

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 ...

Antibacterial action of chitosan and carboxymethylated chitosan
Journal of Applied Polymer Science, 2000A series of chitosan with different molecular weights obtained by γ-irradiation depolymerization and another series of deacetylated chitosan were synthesized. Several N,O-carboxymethylated chitosan and O-carboxymethylated chitosan were also produced. The above samples were characterized by Fourier transform infrared spectroscopy (FTIR).
