Sir Mark Welland, Professor of Nanotechnology There's been a lot of hype about nanotechnology, but what is it and what is a realistic expectation of what it can do? Professor Welland will look at how nanotechnology developed, how it is one step in the progress of technology, and at the kind of areas it can be applied to, such as the understanding and treatment of human diseases as well as the more obvious miniaturisation of electronics that provides ever smaller but more complex mobile phones.
