Characterization of antibacterial bacterial cellulose composite membranes modified with chitosan or chitooligosaccharide

Heparinization and hybridization of electrospun tubular graft for improved endothelialization and anticoagulation

“…As seen in Fig. 3A, three peaks at 14.2 • , 16.6 • , and 22.6 • are observed, which are characteristic peaks of cellulose I [35]. There is a broad peak centered at around 22.6 • in the XRD pattern of CA, which is consistent with previous reports [36,37].…”

Antimicrobial Activity of Chitosan Oligosaccharides with Special Attention to Antiparasitic Potential

“…Chitosan is biocompatible, nontoxic, and also has biodegradable proprieties, hence it is broadly studied in many fields [17]. It has been explored for its antibacterial activity against Gram-positive and Gram-negative bacteria [18,19]. Different mechanisms have been proposed for the antimicrobial activity of chitosan, such as the perturbation of ion transport on the microorganisms [19,20].…”

Chemical Modification of Bacterial Cellulose for the Development of an Antibacterial Wound Dressing

“…Although this methodology often allows to develop efficient biomaterials through easy processes, there are a few drawbacks related to the use of leachable agents, such as the maximum amount that can be loaded into the matrix, the stability of low molecular weight compounds, which are often characterized by higher reactivity and volatility (for instance, in the case of antibacterial natural compounds) and the short-term activity, which is dependent on the release profile of such agents ( Giano et al, 2014 ; Deka et al, 2015 ). Another strategy for the development of BC-based antibacterial materials involves the combination of BC with antibacterial polymers such as chitosan ( Lin et al, 2013 ; Kingkaew et al, 2014 ; Wahid et al, 2019b ; Yin et al, 2020 ) and ε-polylysine ( Gao et al, 2014 ). In this case, however, it is fundamental to ensure good compatibility between the two components to avoid phase separation.…”
