New Ways to See and Build Nano-Gadgets from Designer Molecules

If the machines we want to build have active components of the size of atoms and molecules, fundamentally new ways of manufacturing have to be discovered. Bottom-up approaches hold a great promise to revolutionize medicine and engineering. We will be exploring the formation of two-dimensional ordered arrays of molecules that build themselves by a process called molecular self-assembly. By adjusting the length of the molecules legs the mesh size can be controlled with practical applications ranging from biological sensors to photovoltaic and quantum computing.
