These new biomaterials, produced with environmentally friendly techniques, develop economically valuable uses for biomass and, at the same time, address important socio-economic problems. To do so, we use biosourced carbohydrate blocks in order to:
- Engineer and control the architecture of oligo/polysaccharide-based molecules that lead, via the self-assembly mechanism, to biomaterials: nanoparticles and nano-organized thin films.
- Valorize the biomass as an alternative renewable source of materials (use of natural macromolecules) instead of those produced by oil-chemistry.
This is a real challenge, strongly motivated by the potentials offered by mimicking Nature and by exploiting, at the nano scale level, the potential of oligo- and polysaccharides towards the developments of novel :
- Glyco-nanoparticles (their encapsulation and 'decoration' or 'coating'): Design and control of the shape, their encapsulation with hydrophobic/hydrophilic active molecules, their decoration/coating with specific sugars and their ability to interact via specific sugars with proteins.
- Glyco-nano-organized thin films (long-range 2D & 3D order): Explore the conditions under which, the different microphases, the film thickness and the long-range order on 2D & 3D levels (defect-free) and micro-domain orientation, as well as other factors (annealing, temperature) can be controlled.
- Smart surfaces and manipulations: characterization of the nano-organized thin films and highlight/quantify the interactions.
