This month, the University of Nottingham hosted a university wide outreach event, Wonder 2017, presenting a wide range of exciting science activities to highlight the research taking place at the university. As part of the stand from the Division of Regenerative Medicine and Cellular Therapies, members of the Zelzer group participated in the event by showing visitors how alginate gels are made and how Raman spectroscopy can be used to distinguish different polymers. We also helped out in an activity that explained targeted drug delivery and the spread of viruses and bacteria through sneezing. Bin, Anne, Rebeca, Emanuele and Mischa enjoyed the day, even if it felt more tiring than a day in the lab at the end.
