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.
