''. At the time, it was seen as a potential first step towards applications in mechanosynthesis, where chemical reactions could be manipulated one molecule at a time. Eigler's 2002 research, along with Andreas J. Heinrich, used a cascade of collisions of carbon monoxide molecules to perform logic operations. Eigler graduated from the
