Using folded DNA to precisely place glowing molecules within microscopic light resonators, researchers at Caltech have created one of the world’s smallest reproductions of Vincent van Gogh’s The Starry Night, containing 65,536 pixels and only the width of a dime across. DNA origami, developed in 2006 by Caltech’s Paul Rothemund, PhD (BS ‘94), is a technique that allows researchers to fold a long strand of DNA into any desired shape. The process has the potential to influence a variety of applications, from drug delivery to the construction of nanoscale computers.
