Abstract

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 was demonstrated by performing different attaching assays and phalloidin staining. After interaction with blood the hemocompatibility of the XG-PVA film was evaluated by using a multiparametric approach. Antimicrobial activity of the film against Escherichia coli (E.coli) was tested, and we found that XG-PVA film promotes bacterial retentivity and provides mechanical protection against bacterial infiltration. After loading the film with ampicillin, an inhibitory E. coli growth zone was observed. All together these results indicate that the manufactured film is a promising material to be tested in vivo for wound healing applications
