AbstractBio-aerogels are highly porous, nanostructured materials with a large internal surface area; they are obtained with non-toxic processes from solutions and hydrogels of polysaccharides. The project is at the interface of materials science (biobased polymers, aerogels, 3D printing), chemistry (polymer functionalization) and biomedical applications (wound dressings, controlled release). The principle of additive manufacturing will be used to make the aerogels. A new approach, phase separation, will be tested to shape the material, which allows the use of cellulose, chitosan and their interpenetrating networks. Relevant drugs (e.g. antibiotics) will be incorporated in the aerogels physically (mixing, impregnation) and chemically (polysaccharide functionalization and grafting with cleavable links). The potential of bio-aerogels printed as drug-releasing wound dressings will be evaluated in vitro and, depending on the results, in vivo.
