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
