Paolo Actis is Associate Professor of Bio-nanotechnology at Leeds University. His research involves working at the level of individual cells to diagnose or treat a disease or medical condition. His talk will cover surgery carried out at the nanoscale, and how it is possible to manipulate something so small as a single cell. While it may sound as though it comes from the realm of science fiction, Dr Actis will also talk about his research into nano-injections and nano-scale sensors used to detect disease.
