Extended Data Fig. 6 |. Bright-field optical microscopy image of aggregated NLCO filamentous structures for SDS concentrations above CMC.

In a 1 wt% SDS aqueous solution, the NLCO drops exhibit similar but more complicated shape transition behaviors than those below CMC (critical micelle concentration), i.e., after cooling from 90 °C to 20 °C. For example, aggregated filamentous structures form and sometimes stick to the substrate due, in part, to micelle-induced depletion. (For comparison, expanded filamentous structures form in aqueous solutions below CMC, see example in Fig. 1h in the main text.) The scale bar is 20 μm.
