Our research is driven by the desire to understand the interaction of microorganisms and cells with polymer materials to inspire the development of environmentally friendly antifouling and biomedical coatings. Surface modification and polymer synthesis in conjunction with advanced surface characterization is used to correlate surface properties with biological response for a knowledge driven development of new coating technologies. To gain a deeper insight into the structure and dynamics of surface colonization by microorganisms, we develop and apply microfluidic assays, 3D tracking techniques, and X-ray nanoanalysis.
Jana and Lisa attended the AVS68 in Pittsburgh, both giving a talk. Jana presented her work on tuning the amphiphilicity of alginic acid-based polyelectrolyte multilayers to enhance marine fouling resistance, and Lisa talked about the anti-fouling properties of amphiphilic zwitterionic hydrogels.
Jana and Samantha presented their research at the 5th Young Materials Researchers Day. Jana gave a talk about tuning the amphiphilicity of alginic acid-based polyelectrolyte multilayers to enhance marine fouling resistance, and Samantha won a poster prize for her poster about NO-releasing hybrid polymers. Congratulations!
