Manipulating nanoparticles with light isn’t unheard of. Scientists have long been illuminating and pushing around particles coated with light-activated molecules. But using light to manipulate particles without this type of responsive coating hasn’t been demonstrated previously.

Now, Rafal Klajn of Israel’s Weizmann Institute of Science and coworkers have developed an approach to reversibly draw together and disperse non-light-responsive particles in solution by shining light on them (Nat. Chem. 2015, DOI: . . .
