Caltech Scientists Control Complex Nucleation Processes Using DNA Origami Seeds

The construction of complex man-made objects–a car, for example, or even a pizza–almost invariably entails what are known as “top-down” processes, in which the structure and order of the thing being built is imposed from the outside (say, by an automobile assembly line, or the hands of the pizza maker). “Top-down approaches have been extremely successful,” says Erik Winfree of the California Institute of Technology (Caltech).
