Exploring the potential of nanocellulose-based materials in advanced wound dressings: recent developments and prospects

Rapid development in the field of nanostructured materials has triggered the fabrication of advanced wound dressings to overcome the limitations of current wound therapy. Among these nanomaterials, nanocellulose has gained extensive attention because of its diverse range of structures, ranging from rod-like cellulose nanocrystals to lengthy and entangled cellulose nanofibers, and a unique 3D network of bacterial nanocellulose. In addition, nanocellulose exhibits unique properties and excellent biocompatibility. Recent advances in nanocellulose, particularly nanocellulose composite materials, for advanced wound dressings are discussed in this study. Technological advances, challenges, and prospects of nanocellulose-based advanced wound dressings have been comprehensively explored and summarized.
