DESCRIPTION:Abstract:\n\nMolecular brushes are branched macromolecules whos
 e architecture is similar to that of a bottle brush. This class of materia
 l is ubiquitous in nature and is often found in mucinous fluids of mammals
  and plants where they act as lubricating agent\, antifouling or trapping 
 coatings. These intriguing properties have drawn a lot of attention from p
 olymer scientists and numerous novel applications of molecular brushes hav
 e been identified in optics\, nanomedicine or mechanics. During the past f
 ew years we have been investigating the behavior of molecular brushes at t
 he solid liquid interface and more recently in biological media using a st
 ructure-property relationship approach. We have systematically compared mo
 noblock versus multiblock molecular brushes and evaluated their lubricatin
 g and antifouling properties in a wide range of media. Using surface sensi
 tive techniques such as the Surface Forces Apparatus\, we were able to rat
 ionalize the correlations between polymer architecture\, conformation and 
 interfacial properties. Our more recent work aims to study the properties 
 of these materials in living organisms\, especially at the surface of cart
 ilage and in the blood stream. Our advances in that area show that molecul
 ar brushes are excellent candidates as nanocarriers for drug delivery to t
 he brain as well as good chondroprotective agents.\n\nBio:\n\nPr Banquy is
  an Associate Professor of Pharmaceutical Sciences at the University of Mo
 ntreal\, Canada and director of the Drug Formulation Analisis research clu
 ster. He holds the Tier2 Canada Research Chair in bioinspired materials an
 d is currently the coordinator of an international consortium in articular
  nanotherapy funded by FRQS through the Euronanomed initiative. His resear
 ch activities explore the behavior of soft matter at (bio)interfaces. In r
 ecent years\, his group has been especially interested in the study of sof
 t nanoparticle interactions with living matter and their implications in n
 anomedicine. In this area his research intents to identify which physical-
 chemical cues allow nanoparticles to translocate through biological barrie
 rs and to navigate in dense tissues. His group is also involved in the des
 ign of biomimetic materials for lubrication\, adhesion and antifouling app
 lications. His team has designed several lubricating polymers that are cur
 rently translated to the biomedical field and peptide based materials that
  could be used as strong tissue adhesives.\n
