Electrospun Cactus Mucilage/Poly(vinyl alcohol) Nanofibers as a Novel Wall Material for Dill Seed Essential Oil (Anethum graveolens L.) Encapsulation: Release and Antibacterial Activities
This study, a collaboration work with University of Sfax and Grenoble INP, aimed to create long-lasting molecular carriers by producing electrospun nanofibers from cactus mucilage and poly(vinyl alcohol) loaded with dill seed (Anethum graveolens L.) essential oil (DSEO). The electrospun nanofibers enabled controlled long-term release of DESO. The DSEO-containing nanofibers demonstrated bacteriostatic and bactericidal activities […]
Enantioselective membranes prepared by electrospinning of cellulose tris(3,5-dimethylphenyl carbamate) having various degrees of polymerization: effect of the DP on the morphology
Recently, we reported a proof of concept of enantioselective membrane filtration using a nonwoven membrane prepared by electrospinning of cellulose tris(3,5-dimethylphenyl carbamate) (CDMPC) synthesized from microcrystalline cellulose. In the present work, CDMPCs having higher degrees of polymerization were synthesized from cellulose fibers derived from hardwoods by a collaboration with Centre Technique du Papier granted by […]

Moustoifa Said thesis defense on March 21th, 2023
Abstract: “In regenerative medicine, the implantation of combined of cells and hydrogels is a promising strategy to improve cell therapy. However, it is crucial to monitor the in vivo fate of hydrogels and cells using non-invasive imaging tools, for optimizing their properties as well as for enabling translation into the clinic. In this context, we proposed […]

PhD position “Custom chemical glycosylation of recombinant proteins”
The aim of this PhD project is to develop a versatile chemical approach to protein glycosylation using the unique reactivity of natural but scarce amino acids. We are looking for a candidate with a strong interest in interdisciplinary projects at the interface between chemistry and biology. He (She) must have advanced knowledge in organic chemistry, […]
Design of hyaluronan-based dopant for conductive and resorbable PEDOT ink
Abstract “Conformable biocompatible conductive materials are increasingly sought for the development of bioelectronics. If additionally resorbable, they could serve for the design of transient implantable electronic devices, opening the way to new healthcare applications. Hyaluronan (HA) derivatives including sulfate and aminophenylboronic acid (PBA) groups (HAS-PBA) were therefore designed to serve as dopants of poly(3,4-ethylenedioxy)thiophene (PEDOT). […]
Biomass in the Bioeconomy
Abstract: “Biomass is the physical basis of the bioeconomy, the renewable segment of the circular economy, and as a CO2-neutral part of the carbon cycle, biomass is an efficient carbon sink. Demand for biomass is increasing worldwide because of its advantages in replacing fossil-based materials and fuels, which presents the challenge of reconciling this increased […]
Extending Janus lectins architecture: Characterization and application to protocells
Abstract: “Synthetic biology is a rapidly growing field with applications in biotechnology and biomedicine.

Thus far, the development of photosynaptic devices via green processing using biobased materials has become a major challenge, owing to restrictions in complex architecture, material design, and stimulation wavelength. This […]
Paul Rivollier thesis defense on February 28th, 2023
Summary : “Influenza viruses are responsible for human flu epidemics and pandemics causing hundreds of thousands of deaths each year, or sometimes long-term sequelae. The infectious process is based notably on two proteins, hemagglutinins and neuraminidases. The first allow the adhesion of the virus on the epithelial cells of the human respiratory system by the interaction […]
Supramolecular carbohydrate-based hydrogels from oxidative hydroxylation of amphiphilic β-C-glycosylbarbiturates and α-glucosidaseinduced hydrogelation
The team “Self-assembly of Glycopolymers” of CERMAV has developed a new family of sugar derivatives through an eco-responsible process which is able to self-assemble into hierarchical glyconanostructures to ultimately gel water and the gelation can be triggered by the action of a glycosidase.

Hijacking the Peptidoglycan Recycling Pathway of Escherichia coli to Produce Muropeptides
Muropeptides are short peptidoglycan fragments released from the cell wall of bacteria as part of their metabolism or as a result of biological stresses, in which they play a major role in the induction of antibiotic resistance. In order to better understand these processes, we developed a new synthetic approach which combines synthetic biology and glycochemistry to prepare Gram (–) and Gram (+) muropeptides.
