Understanding and engineering the self-assembly of soft colloidal
particles (microgels) at liquid–liquid interfaces is broadening their
use in colloidal lithography. Here, we present a new route to
assemble rectangular lattices of microgels at near zero surface
pressure relying on the balance between attractive quadrupolar
capillary interactions and steric repulsion among the particles at
water/oil interfaces. These self-assembled rectangular lattices are
obtained for a broad range of particles and, after deposition, can be
used as lithography masks to obtain regular arrays of vertically
aligned nanowires via wet and dry etching processes.
