Advancement of chitin and chitosan as promising biomaterials
2022, Journal of Saudi Chemical SocietyChitosan crosslinking with a vanillin isomer toward self-healing hydrogels with antifungal activity
2022, International Journal of Biological MacromoleculesCitation Excerpt :The biodegradation behavior of the hydrogels was evaluated in terms of weight loss over a period of 21 days, in conditions mimicking the environment of infected wounds: lysozyme solution of pH 8.5 at 37 °C (Fig. 13) [4]. The lysozyme was chosen due to its presence in wound fluid, and its ability to hydrolyze the chitosan into oligomers [59,60]. The most promising samples for in vivo applications were chosen for this study (Fig. 13).

2020, International Journal of Biological MacromoleculesCitation Excerpt :It is worth mentioning that chitosan derivatives containing cationic sulfonium saltsinvestigated herein turned out to have excellent antioxidant activity against DPPH-radical, hydroxyl-radical, and superoxide-radical. In this study, as a befitting intermediate, the Br-CS was first synthesized by the reaction between chitosan and bromoacetyl chloride [15–17]. Subsequently, the thioether groups were introduced into Br-CS through the reaction of alkylate to obtain chitosan derivatives containing cationic sulfonium salts [18].
