Ljiljana Fruk is a Reader in BioNano Engineering in the Department of Chemical Engineering and Biotechnology, University of Cambridge. She has taught bionanotechnology in Germany and the UK, both at undergraduate and postgraduate level. Her group works on the design of enzyme-like catalysts, hybrid biopolymers for applications in sensing and optoelectronics, as well as drug nanocarriers for senescent cells and hard-to-treat cancers. A Fellow of the Royal Society of Chemistry and Council member of the Cambridge Philosophical Society, Dr Fruk is also a science populariser and co-editor of the book Molecular Aesthetics (with Peter Weibel, 2013). Antonina Kerbs is a scientific team coordinator at Miltenyi Biotec, Germany. Before joining Miltenyi in 2019, she was a postdoctoral researcher in Dr Fruk's group in the Department of Chemical Engineering and Biotechnology, University of Cambridge, where she worked on the preparation and biofunctionalisation of nanoparticles, and the designing of biosensing devices.
