Formation of OEG(BzlS)2 coacervates. A Photographs of (i) a DMSO solution of OEG(BzlS)2, (ii) an aqueous dispersion containing OEG(BzlS)2, and (iii) an aqueous solution of OEG(BzlSO)2 in glass vials with 200 µL inserts. B Concentration-dependent turbidity (absorbance at 600 nm) of OEG(BzlS)2 and OEG(BzlSO)2. C Representative microscopy images (DIC) of OEG(BzlS)2 coacervates. D Time-lapse microscopy images of OEG(BzlS)2 coacervates showing a coalescence event (a magnified part of Supplementary Movie S1; see also Supplementary information Fig. S8 for whole images at selected times). Conditions: [OEG(BzlS)2] = 10 mM in 100 mM phosphate buffer (pH 7.5)/DMSO (v/v = 9:1), ambient temperature. Scale bar: 30 µm for (C) and 10 µm for (D)
