Handcrafting nanoparticles into superstructures with light

March 1, 2011

One of the Holy Grails of modern nanoscience is to assemble nanoparticles—tiny pieces of matter with diameters in the billionth of a yard range—into larger structures of any desired shape and form at will. Argonne scientists have recently demonstrated a remarkably simple, elegant and cost-effective way of achieving this goal by using a process they term "optically directed assembly," or ODA. More »
