SEMINAR SPEAKER
Victor N. Vasilets Ph.D., Dr. Sci.
Research Professor, Drexel Plasma Institute

ABSTRACT
Plasma and vacuum ultraviolet (VUV) - assisted engineering provides the possibilities to design a wide range of physical and biological surface properties for task-oriented modification of medical polymers. Different plasma and VUV-assisted techniques provide effective methods for cleaning, sterilization and biological functionalization of medical polymers. In this talk the applications of plasma and VUV-assisted photo-oxidation, post-chemical treatment, micro-patterning and graft-polymerization of biologically active functionalities for regulation of protein adsorption and platelet adhesion as well as improvement of haemocompatibility of medical polymers will be presented.

BIOSKETCH
Dr. Victor N. Vasilets received his M.S. and Ph.D. in Physics and Mathematics from Moscow Institute of Physics and Technology, Russia (1976, 1979) and Dr. Sci. degree in Chemistry from the N.N. Semenov Institute of Chemical Physics, Russian Academy of Sciences, Moscow, Russia (2005). He joined N.N. Semenov Institute of Chemical Physics, Russian Academy of Sciences in 1979 as a Research Scientist, Senior Research Scientist and Principal Research Scientist. He was invited as a Research Professor at Center of Biomaterials, Kyoto University, Kyoto, Japan (1996), Institute of Polymer Research, Dresden, Germany (1998-2000), Plasma Physics Lab, University of Saskatchewan, Saskatoon, Canada (2002-2005). In 2005 he joined Drexel Plasma Institute at Drexel University. His present research interests have focused on using plasma and vacuum ultraviolet irradiation for sterilization, wound treatment and biological functionalization of medical polymers. He is a member of Editorial Board of the International journal 'Plasma Processes and Polymers'
