Large wounds are characterized by clini-cal and surgical challenges, requiring numeroussearches on demand for inexpensive biocompatiblematerials that produce the best quality of cutaneoushealing. Cellulose is a biopolymer of greatest abun-dance, good biocompatibility and wide applicationdue to its chemical and physical properties. This studywas aimed to develop and characterize low costmembranes of wood cellulose nanofibrils for potentialapplication as a wound dressing in comparison to acommercial porous regenerating membrane. An inex-pensive mechanical method was used to defibrillatecellulose, and later the membranes were obtained fromthe nanofibrils by filtering and drying under mildpressure. The techniques employed for characteriza-tion included scanning electron microscopy, physicaltesting, application in vivo and cost-effectivenessanalysis. The membranes presented promising phys-ical properties for application as cutaneous dressing,with characteristic translucency allowing the evalua-tion of the wound without the need of removal andexchange of the dressing. Wood nanocellulose dress-ing seems to be promising for wound care since itpresented good adhesion to the moist wound surfacesthus promoting the most efficient repitialization in thefirst 4 days. No allergic reaction or inflammatoryresponse to wood nanocellulose dressings wasobserved. The wood nanocellulose membranes standout as a potential wound dressing, as it shows similarefficacy of bacterial cellulose dressing. Besides theefficacy, the membrane developed in this studypresents a simpler, faster and cheaper manufacturingprocess, which may reduce the production cost by99% MenosLarge wounds are characterized by clini-cal and surgical challenges, requiring numeroussearches on demand for inexpensive biocompatiblematerials that produce the best quality of cutaneoushealing.
