Mobility project

Preparation and characterization of nanostructures with polysaccharides from edible mushrooms

Increasing environmental awareness and limitation of petroleum resources stimulate research dedicated to bio-based materials with low environmental impact and innovative functionality. The living world can be a fruitful source of inspiration and my project is aimed at the preparation and characterization of nanostructures containing polysaccharides extracted from natural sources.

Two naturally occurring polysaccharides, chitin nanocrystals and xyloglucan, will be assembled onto multilayer thin films using the spin-assisted layer-by-layer procedure. The adsorption process and interactions between xyloglucan and chitin will be examined, and the impact of experimental parameters on film growth will be studied, including rinsing step, chitin concentration, and ionic strength. The resultant films will be characterized in order to obtain information about the molecular arrangement, surface coverage, thickness, roughness, etc.

Biography & research interests

I graduated with a degree in Chemistry from Zaragoza University (Spain) in 2003 and undertook a Physical-Chemistry training fellowship at the Department of Organic and Physical Chemistry in Zaragoza University. During 2005-2006, I performed two research stays as a pre-doctoral student at the Chemistry Department of Durham University, focused on the synthesis of conjugated organic molecules, and at the Molecular Electronics Centre of Cranfield University (United Kingdom) aimed at the study of electrical properties of nanostructures. In 2008, I obtained a European PhD from Zaragoza University, concentrating on the fabrication and characterization of thin films containing conjugated organic derivatives. Following my PhD, I undertook a 5 year researcher position at the Centre for the Food Quality (INIA) in Soria (Spain) and actively collaborated with the Centre setting-up and establishment of research lines, conducting studies on emerging projects on bioactive components from natural products. I participated in several collaborative projects with private companies as well as in several national research projects focused on food properties and characterization of bioactive substances from edible materials.

In 2013, I undertook a 1 year post-doctoral position at the Research Unit of Biopolymers, Interactions and Assemblies at the French National Institute for Agricultural Research in Nantes aimed at the development of multilayer films containing polysaccharides obtained from natural sources.
