Polyelectrolytes are polymers that display repetitive charged units. A fundamental feature of polyelectrolytes is their capacity to respond to changes in the ionic strength by changing conformation. Polyelectrolytes can be easily complexed with other charged molecules through electrostatic interactions, and assembled or patterned on surfaces, which makes them ideal blocks for nanofabrication. In this presentation we will review research conducted in our group concerning different applications of polyelectrolytes in the fields of biomaterials and nanomedicine. We will show the use of polyelectrolytes in Layer by Layer (LbL) assemblies for the fabrication of supported lipid membranes and artificial virus nanoparticles. We will explore as well the LbL assembly for tuning surface adhesion of cells and for creating antibacterial coatings. The complexation of polyelectrolytes with nucleic acids and the fabrication of polyamine phosphate supramolecular nanoparticles as pH-responsive non-viral vectors for gene therapy will be presented. Finally, we will show how pH and temperature sensitive charged nanogels made from polyacrylic acid and polyisopropylacrylamide respond to different stimuli and complex with charged molecules. Throughout the presentation different aspects of the physical chemistry of polyelectrolytes will be discussed.

Sergio E. Moya studied Chemistry at the National University of the South, Argentina.
He got a PhD in Physical Chemistry, Magna Cum Laude, working at the Max Planck Institute of Colloids and Interfaces, Golm, Germany under the supervision of Helmuth Moehwald and Edwin Donath.
He did his post doc at the College de France, in the group of Jean Marie Lehn and at the Nanoscience centre at the University of Cambridge, UK. After UK he worked as independent researcher at the Centre of Applied Chemistry in Mexico for 2 years. Since 2007 he is group leader at CIC biomaGUNE, a center of biomaterials located at San Sebastian, Spain. He has been Adjunct Faculty at Zhejiang University, China. He is the author of 230 papers in Material Science, Nanotechnology and Chemistry and he has coordinated several EU and international projects. His research interests cover the use of polyelectrolytes in nanofabrication, self assembly, hybrid materials, physical chemistry, nanomedicine, and fate of nanomaterials
