Negatively charged colloidal nanospheres (left) and DNA (right) self assemble along contours of like‐charged SiO 2 domains patterned in a fluidic nanoslit. The attractive interactions driving this static self‐assembly process manifest in solution at low ionic strength and slit depths of around 100 nm. Scale bar represents 10 µm.
