Size-selected atomic clusters are prepared and mass-filtered using novel cluster beam systems then deposited with controlled energy onto well-defined solid surfaces. Deposited clusters (of both metals and semiconductors) are imaged with STM or aberration-corrected scanning transmission electron microscopy, which yields a 3D atomic map. The clusters are exploited in various ways: for example, to immobilise individual protein molecules, as relevant to biochips for early cancer detection, to function as novel catalysts for selective chemistry and to create novel electronic or optical coatings, e.g., for fuel or solar cells. An exciting and very high risk new project seeks to scale up the production rate of size-selected clusters by 10 orders of magnitude!
