Crack formation in a colloidal nanoparticle film can be harnessed by restricting the drying of the colloidal suspension using a flow‐enabled self‐assembly (FESA) strategy to yield large‐area periodic cracks (i.e., microchannels) with tunable spacing. In their Communication on page 4554 ff., Z. Lin and co‐workers also show that these uniform microchannels can be utilized as a template to guide the assembly of Au nanoparticles, forming intriguing nanoparticle threads.
