Two teams have recently reported that gold nanoparticles, loaded with DNA sequences on their surface, can be induced to form defined three‐dimensional crystals through duplex formation (see image) between “sticky ends”. Crystallites up to several micrometers in size are detected by small‐angle X‐ray scattering. The work is discussed in this Highlight.
