Self-cleaning glass - such as the roof of St Pancras
station - has revolutionised architecture. UCL materials
scientist Charlie Dunnill is taking this technology one step

talks to the Wellcome Trust's Hugh Blackbourn about how
materials science is paving the way for more hygienic conditions in
our hospitals.
