AbstractBio-aerogels are highly porous, nanostructured materials with a large internal surface area; they are obtained via 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 crosslinking) and biomedical applications (wound dressings, controlled release). Hyaluronic acid will be printed into hydrogels using a support bath, which avoids the disadvantages of conventional printing-in-air, including clogging of the printing nozzle and gravity-induced structural collapse during printing. Relevant drugs (e.g. antibiotics) will be incorporated in the aerogels physically via mixing and impregnation. The potential of the bio-aerogels as drug-releasing wound dressings will be evaluated using in vitro and ex vivo models.
