1. A method, comprising:
with a ternary mixture of a hydrophilic phase, an organic phase, and a co-solvent, the ternary mixture further having a plurality of particles disposed therein,
giving rise to evaporation of the co-solvent into the environment exterior to the ternary mixture,
the evaporation effecting (1) a phase separation that forms an interface between the hydrophilic phase and the organic phase, and (2) an assembly of at least some of the plurality of particles at the interface,
the assembly arresting the phase separation and the evaporation giving rise to a multiphasic three-dimensional structure,
the multiphasic three-dimensional structure defining a plurality of domains therein.
