Journal ArticleDOI
Thymine-modified chitosan with broad-spectrum antimicrobial activities for wound healing.
TL;DR: In this article, four water-soluble thymine-modified chitosan (TC) derivatives with the degree of substitution (DS) ranging from 0.23 to 0.62 were synthesized and freeze-dried to obtain porous sponge dressings.
Journal ArticleDOI

Rapid Hemostasis Resulting from the Synergism of Self-Assembling Short Peptide and O-Carboxymethyl Chitosan.
Ruirui Hao,Xiaoting Peng,Yan Zhang,Jiaxi Chen,Tong Wang,Wenxin Wang,Yurong Zhao,Xinglong Fan,Cuixia Chen,Hai Xu +9 more
TL;DR: This study demonstrated that transglutaminase-catalyzed reactions not only occurred among designed short peptide I3QGK molecules but also between the peptide and a natural polysaccharide O-carboxymethyl chitosan, eventually leading to rapid hemostasis.
Journal ArticleDOI
Chitosan-laponite nanocomposite scaffolds for wound dressing application.
Virgínia de Alencar Muniz Gonzaga,Alessandra Lima Poli,Juliana Dos Santos Gabriel,Daiane Y. Tezuka,Talita Alvarenga Valdes,Andrei Leitão,Camila Fernanda Rodero,Taís Maria Bauab,Marlus Chorilli,Carla C. Schmitt +9 more
TL;DR: The results suggested that the nanocomposite scaffolds are biomaterials potentially useful as wound dressings as well as bioadhesion, antibacterial activity, viability, and cell adhesion.
Journal ArticleDOI
Preparation of graphene-embedded hydroxypropyl cellulose/chitosan/polyethylene oxide nanofiber membranes as wound dressings with enhanced antibacterial properties
Che-Min Lin,Yung-Chi Chang,Li-Chang Cheng,Chao-Hsien Liu,Shin C. Chang,Tzu-Yang Hsien,Da-Ming Wang,Hsyue-Jen Hsieh +7 more
TL;DR: Electrospun nanofiber membranes possessed good mechanical properties, appropriate WVTR and high water absorption thus suitable for absorbing wound exudate, and exhibited nontoxic, anti-fibroblast adhesion and anti-bacterial properties.

Chitin and Chitosan Preparation from Marine Sources. Structure, Properties and Applications
Islem Younes,Marguerite Rinaudo +1 more
TL;DR: Several selected pharmaceutical and biomedical applications are presented, in which chitin and chitosan are recognized as new biomaterials taking advantage of their biocompatibility and biodegradability.
Journal ArticleDOI
Preparation and antibacterial activity of chitosan nanoparticles.
TL;DR: Results show that chitosan nanoparticles and copper-loaded nanoparticles could inhibit the growth of various bacteria tested and exposed to S. choleraesuis led to the disruption of cell membranes and the leakage of cytoplasm.
Journal ArticleDOI
Antibacterial activity of chitosans and chitosan oligomers with different molecular weights.
TL;DR: Antibacterial activities of chitosan was inversely affected by pH (pH 4.5-5.9 range tested), with higher activity at lower pH value, and bactericidal effects with gram-positive bacteria than gram-negative bacteria in the presence of 0.1% chitOSan.
