Advances in Polysaccharide Materials

Polysaccharides are very diverse in their structure and function; they are widely distributed in nature and are produced by all organisms, plants, animals and microorganisms. Natural polysaccharides (cellulose, starch, hemicelluloses, pectin, chitin, chitosan, alginic acid, carrageenan, etc.) have excellent characteristics, including biodegradability and biocompatibility, which make them extremely attractive for many applications. The presence of different functional groups in the polysaccharides thus allows various chemical or enzymatic modifications, which offer practically limitless options for developing new compounds that are better suited to the targeted applications.

Introduction
Bio
Patrick Martin was born in Abbeville (France) in 1963. He received his Ph.D. degree from the University of Picardie-Jules Verne in 1993 under the supervision of Professor P. Villa in the field of raw materials and glycochemistry. In 1994, he became Assistant Professor at the University of Picardie-Jules Verne in the Laboratoire des Glucides where he worked on amphiphilic glycomolecules and in biological oligosaccharides synthesis. In 2000, he received his Habilitation and was promoted Professor in 2001 at the University of Artois. He manages the Unit Transformations&Agroressources (ULR7519) at Artois University. His current research interests are mainly in the field of bio-based chemistry (biomolecules and biopolymers) and reactivity like glycochemistry (surfactants, liquid crystals, drug targeting, polyphenols, …) and biomaterials. He is the author of 110 international scientific publications and 5 patents.

Introduction
Bio
Nicolas Joly received the Ph.D. degree from the University of Limoges, Limoges, France, in 2003.,His work was dedicated to the chemical modifications of cellulose, more precisely to the crosslinking of cellulose by olefin metathesis. In 2004, he became an Assistant Professor with the IUT of Béthune, University of Artois, Arras, France, where he was promoted as a Professor in 2012. His research activities are mainly focused on bio-based plastics and composites, obtained by the chemistry of natural polysaccharides such as cellulose, starch, inulin, chitin, and chitosan. He joined the Transformations & Agroressources Unit, Artois site (ULR 7519), Béthune, France, in 2018.

Centro de Investigaciones en Química Biológica- CONICET and Universidad Nacional de Córdoba, Córdoba, Argentina

Introduction
Bio
Dr. Fanani graduated from Biochemistry in 1996 at FCQ-UNC and began her doctoral studies under the direction of Dr. Bruno Maggio under the theme “Supramolecular modulation of the activity of sphingomyelinase in biointerphases”, which ended in 2001 and for which he received the Dr. Agustin Marenzzi Prize, 2000/2001 awarded by the Faculty of Pharmacy and Biochemistry, Univ. Buenos Aires. She also developed a brief postdoctoral work following this subject in Dr. Maggio. During 2003-2005, she developed studied on “Lipid Modulation of the Diacylglycerol Kinase Activity of α – and γ -Isoforms” under the supervision of Dr. Richard Epand at McMaster University (Canada). After her return, she obtained a position as Assistant researched (2005) and then as Associate Researcher of CONICET (2008) at CIQUIBIC, focusing her studies on the interfacial restructuring suffering by lipid membranes when they are subjected to the action of lipolytic enzymes. In this way, she deepened in the study of the structural (domain formation), rheological and thermodynamic properties of model lipid membranes (mainly lipid monolayers), in particular those containing simple sphingolipids such as ceramide and sphingomyelin. Currently she holds the position of Associate Professor and Independent CONICET Researcher at CIQUIBC, focusing her research on the interaction of amphiphiles of pharmacological interest with model lipid membranes, and how such interaction depends on both the drugs properties and the biophysical properties of the target membrane She has published over forty papers in international scientific journals, of which eight are reviews and has received more than 735 citations (index h 17). Dr. Fanani has received numerous trainees in her laboratory primarily interested in visualizing lipid monolayers by Brewster angle microscopy, which has led to collaborations with the National Univ. South Univ. of Habana, the Univ. of Sao Paulo, Brazil and the Univ. of the Basque Country.

Univ Rennes, CNRS, Ecole Nationale Supérieure de Chimie de Rennes, Rennes, France

Introduction
Bio
Thierry Benvegnu is a University Professor at the Ecole Nationale Supérieure de Chimie de Rennes (ENSCR). He graduated from ENSCR in 1989 as an engineer and completed a thesis in organic chemistry at the University of Rennes 1 under the supervision of Dr. René Grée as part of a project financed by the Servier laboratories. After a post-doctoral internship in the team of Prof. Paul Wender at Stanford University (USA, 1993-1994), he obtained a position as a lecturer at ENSCR and was appointed Professor of Universities in the same institution in 2004 (Professor of Universities with exceptional status since September 2017). His research activities are based on two themes: the synthesis and physicochemical characterisation of Archaea membrane lipids as nanovectors for active ingredients and nucleic acids and the 'green/blue' chemistry of 100% biodegradable biobased surfactants. He is scientific advisor and co-founder of the start-up SurfactGreen, which specialises in the production and formulation of surfactants based on terrestrial and marine plant raw materials.
