The Atomic Force Microscope (AFM), which uses a fine-tipped probe to scan surfaces at the atomic scale, will soon be augmented with a chemical sensor. This involves the use of a hollow AFM cantilever, through which a liquid - in this case mercury - is passed under pressure. The droplet of mercury at the tip acts as a sensor. This microscopic fountain pen was developed by researchers at the University of Twente's MESA+ Institute for Nanotechnology.
