Theres plenty of room at the bottom - What impact is Irish technology having on our lives and what are the tangible results of Irish research? Prof. Shane Bergin guides us through the field of nanotechnology which is shaping our modern world and where Irish research, at centres like CRANN in Trinity College Dublin, is leading. Shane looks at the scientists breaking ground in nanoscience and the implications of their work, from software systems developed in Limerick, to the future of drug manufacturing and building robots to assist dementia patients.
