Solid chiral microspheres with unique and multifunctional optical properties are produced from cholesteric liquid crystal‐water emulsions using photopolymerization processes. These self‐organizing microspheres exhibit different internal configurations of helicoidal structures with radial, conical or cylindrical geometries, depending on the physicochemical characteristics of the precursor liquid crystal emulsion.
