Classification: CPC B  C | IPC B

Claim 0:
1. A biliquid material comprising an emulsion comprising a continuous liquid phase, a dispersed liquid phase, and a surface-stabilizing material;
wherein:
the dispersed liquid phase is immiscible with the continuous liquid phase;
the dispersed liquid phase is in the form of a plurality of droplets in the continuous liquid phase;
the surface-stabilizing material is soluble in at least one of the continuous liquid phase and the dispersed liquid phase and the surface-stabilizing material adsorbs at the surfaces of the plurality of droplets, wherein the surface-stabilizing material imparts a repulsive interaction between the plurality of droplets that inhibits coalescence of the plurality of droplets; and
the biliquid material has a ordered structurally-colored droplets structure, wherein the ordered structurally-colored droplets structure yields one or more structural colors when illuminated with broad-spectrum light; and
the one or more structural colors arise from diffraction of the broad-spectrum light by the plurality of droplets.
