    03-2020 Laurianne Legay joined the BIO group as a PhD student to work on the ANR JCJC project '3D-AER-HYAL' focusing on hyaluronic acid aerogels for wound dressing applications. Welcome!

    04-2021 The BIO group published 7 articles so far in 2021. More details can be found here!

    Academic projects

    3D-AER-HYAL: 3D printing of hyaluronic acid aerogels as on-demand removable wound dressings (March 2021 - February 2024)
    The objective of this project is the preparation of on-demand removable, hyaluronic acid-based aerogels obtained by additive manufacturing for application as wound dressings which are capable of releasing biologically active agents. 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 project is funded by the ANR JCJC scheme.

    3D printing of biobased polymer aerogels for biomedical applications (October 2019 - September 2022)
    The objective of this project is the 3D printing of bio-aerogels and evaluation of their use as drug-releasing wound dressings. This highly interdisciplinary project is carried out in collaboration with the Institute of Biomolecules Max Mousseron (IBMM), Montpellier, which has extensive experience in the domain of medical devices and controlled release systems. The project is funded by the CNRS 'transversal thesis' program.

    Oligosaccharidic (multi)block copolymers with tunable composition (November 2017 - October 2021)
    The main objective of the project is to widen the possibilities of creating new chemical structures from oligosaccharide blocks by preparing and studying the properties of a new class of (multi)block copolymers based exclusively on the assembly of oligosaccharides bearing different properties. After preparation and thorough characterization, the structure of these block copolymers is related with their physical, physico-chemical and mechanical properties. Collaborations with Université de Picardie et Université de Lyon. The project is funded by the ANR PRC scheme.

    Industrial projects

    Starch porous materials for controlled delivery (started February 2019)
    The objective is to prepare, characterize and understand if and how porous materials from starch can be used as delivery matrices.

    Biomass For the Future (November 2014 - October 2021)
    BFF aims at the development of cropping systems and new varieties of sorghum and miscanthus as well as new markets: energy (heat and methane), polymer composites for the automotive industry and load bearing miscanthus concrete blocks for construction. One of the objectives is to define the optimal combination of raw materials / valorisation thanks to the association of specialists in plant biology, ecophysiology, genomics, material science, life cycle analysis, agronomists, breeders, farmers and process engineers.
