Professor of Chemical Nanoscience Neil Champness explores the future of nanoscale machines. Can we build a machine simply from molecules at the nanoscale? Subscribe for regular science videos: http://bit.ly/RiSubscRibe The idea of building machines that are only nanometres in size is a dream that has formed the basis of Hollywood movies. How realistic is such a goal and how would we go about tackling the challenges that lie in wait? How do we begin to build a machine simply from molecules? Join Neil Champness to explore the future of nanoscale machines.
