Bio-compatible cellulose nanostructures for advanced wound healing applications

This multi-disciplinary research programme will develop novel material solutions for use in advanced wound healing based on nanofibrillated cellulose structures. This proposal requires knowledge on the effective production and application of sustainable and innovative micro- and nanofibres based on cellulose. The project will assess the ability of these nanofibres to interact with complementary polymers to form novel material structures with optimised adhesion and moulding properties, absorbance, porosity and mechanical performance.  The NanoHeal proposal brings together leading scientists in the fields of nanocellulose technology, polymer chemistry, printing and nanomedicine, to produce biocompatible and biodegradable natural polymers that can be functionalized for clinical applications. As a prototype model, the project will develop materials for use in wound healing. However, the envisaged technologies of synthesis and functionalization will have a diversity of commercial and industrial applications.

The project is funded by the Research Council of Norway/NANO2021 (grant no. 219733), and is a cooperation between several leading R&D partners.
