RADIATION CROSSLINKED ADVANCED WOUND DRESSING CONTAINING EGG WHITE PROTEINS

During the past decades, the use of antibiotics has grown worldwide in different fields, from medicine to agriculture, leading to antibiotic resistance of microbes, which is the cause of thousands of deaths every year worldwide. [1, 2] Finding new antibiotics is becoming more and more difficult because their development is no longer convenient in term of the cost–benefit ratio for the pharmaceutical industry. The interest in egg white proteins, such as ovoalbumin, ovotransferrin and lysozyme, has risen especially because of their demonstrated antimicrobial activities. [3] These antimicrobial proteins can then be used to enrich wound dressing films that requires a high level of control of mi…

Xyloglucan-based hydrogel film for wound dressing: Structure and biological properties relationships

2018

Crosslinked xyloglucan-poly(vinyl alcohol) based hydrogel films have been synthetized and characterized for wound healing applications. Polyvinyl alcohol (PVA) and glycerol (Gro) were added to have an optimal combination of softness, conformability and resilience. Physical hydrogel have been transformed into permanent covalent hydrogels by reaction with glutaraldehyde (GA). Chemical and physical properties of the films have been analyzed by different technique. Moreover, biocompatibility of a selected formulation was assessed in vitro by investigating different aspects, such as cell viability, oxidative stress, mitochondrial dysfunction and specific stress biomarkers. Partial adhesiveness w…
