This guest-led webinar, also including a high-level researcher and additional expert, will focus on the surface properties of materials – key parameters in many applications, especially in the biomedical field, to control cell-material interactions. Dr. Urszula Stachewicz and her research group will show how to control surface properties – including the zeta potential of polymer fibers – via a single-step electrospinning process. They will prove the significant effect of fibers' surface potential and geometry on cell integration with scaffolds and further cell development in the regeneration processes based on osteoblast and fibroblast culture studies. They will also explain how the controlled geometries of electrospun fibers and membranes show significant application potential as skin treatment patches.
Urszula Stachewicz (ORCID: 0000-0001-5102-8685) is an associate professor at AGH University of Science and Technology in Krakow, Poland. She graduated from Delft University of Technology with PhD in electrohydrodynamic of liquids to use electrospray as an on-demand deposition method, with research performed at Philips Research Laboratories in Eindhoven, the Netherlands. She conducted the postdoctoral research at Queen Mary, University of London (UK) and work at spin-out company Nanoforce Technology Ltd. discovering polymer science and electrospun fibers. In 2018 she was a Visiting Fellow at the University of Cambridge at Department of Materials Science and Metallurgy, UK. Her research activity is focused on surface properties of electrospun fibers for biomedical and water and energy harvesting, and in situ mechanical testing of synthetic and naturally structured materials. She developed advanced 3D tomography protocols using focus ion beam and scanning electron microscopy (FIB-SEM) for nanofibrous biomaterials and membranes. In 2020 she has been awarded with the ERC StG, BioCom4SavEn (biocom4saven.agh.edu.pl).
