Abstract
Bio-based nanomaterials are defined as materials of biological origin with one or more dimensions smaller than 100 nm. At this small scale, exciting properties start to emerge which leads to materials with a large variety in applications, including environmental remediation, metal waste recycling and theranostics (combined therapy and diagnostics). By modifying the surface of these bio-based nanomaterials it is possible to selectively change the affinity of biomaterials towards different metal ions and mineral oxide nanoparticles. This allows for the production of tailored bio-based hybrid materials. Present work is focussing on two key aspects, (1) metal selectivity and (2) theranostics. One of the aims was in modifying nanocellulose to produce a material suitable for the separation of late transition metals Nickel and Cobalt from Rare Earth elements and the mechanism behind this selectivity. Another track focussed on the introduction of mineral oxide nanoparticles onto cellulose-based nanomaterials derived from cotton or grown by microorganisms and their unique properties for their application as wound-dressing materials.
