This polygonal texture displayed by the smectic liquid crystal is the result of half focal-conic domains that pack to fill the half hemispherical space with bases of the cones located at the aqueous interface of the Janus droplet. We have recently demonstrated that these liquid crystal-generated topological singularities are powerful templates for the spatial organization of biomolecules for biological and sensing technologies (<a rel="nofollow" class="external free" href="https://pubs.acs.org/doi/abs/10.1021/jacs.9b09216">https://pubs.acs.org/doi/abs/10.1021/jacs.9b09216</a>).
