Fig. 2. Comparison between experimental and numerical results for packing of colloids at the interface.

Fig. 2

(A to C) Fluorescence micrographs (under green fluorescent protein illumination) showing change in the packing of the 0.52-μm PS colloids on the surface of ODs as a function of SDS concentration in the bulk of the sample. The colloids go from a colloidal gas-like phase (A) to a liquid-like cluster (B) to a well-aligned hexagonal packing at the interface (C). (D to F) Snapshots for different strengths of the Asakura-Oosawa (AO) potential: VAO = 0 (D), 6 (E), and 8 (F) (simulation details are in the Supplementary Materials). These images were modulated with a Gaussian blur emulating the experimental situation.
