Enhancing the Antibacterial Properties of Chitosan Coatings: Ag@Chitosan and Chitosan from Insects

Coatings
In this study, the electrophoretic deposition (EPD) technique was used to prepare chitosan-based coatings with enhanced antibacterial activity suitable for bone implant applications. We designed, prepared, and compared the physico-chemical and biological properties of coatings obtained with commercial chitosan, chitosan enriched with silver ...

Bio-evaluation of crustacean and fungal nano-chitosan for applying as food ingredient

Toxicology Reports, 2018
Chitosan, bio-polyaminosacharide, is derived from chitin. Two sources (shrimp wastes and fungus biomass) were used to produce chitosan. And then the chitosan was produced in the nano-form followed by characterization by transmission electron microscopy ...

Comparative in vitro evaluation of staining of natural tooth enamel by chitosan, chlorhexidine, and chitosan-chlorhexidine mouthwashes

BMC Oral Health
Background Chitosan mouthwash has antimicrobial and antiplaque properties with lower cytotoxicity than many conventional mouthwashes. Given the well-known side effects of chlorhexidine, particularly tooth discoloration, this study aimed to compare enamel

Ultrasonication of chitosan and chitosan nanoparticles

International Journal of Pharmaceutics, 2003
The objective of this study was to evaluate the effects of ultrasonication on chitosan molecules and nanoparticles. Molecular weight (M(v)) of chitosan HCl (M(v) 146 kDa and degree of deacetylation (DD) 96%) decreased linearly with increasing duration and amplitude of ultrasonication. DD and FTIR absorption were unaffected.
