Extended Data Fig. 7: Selective extraction of a concentrically partitioned PEG mixture.
From: Near-identical macromolecules spontaneously partition into concentric circles
Time-dependent confocal laser scanning microscopy (CLSM) images for λext = 488 nm (NBD); λext = 552 nm (RhB) of a concentrically partitioned 1:1 mixture of terminally different PEGs (MePEG5KNBD and MePEG5KRhB) upon selective extraction. The sample was initially extracted with a flow of milli-Q water for 30 s, followed by a water–methanol mixture (80/20, v/v) for an additional 30 s, and finally a water–methanol mixture (50/50, v/v) for a minute. Residual fluorescent intensity ratios of PEGs are presented at the top left of the images. Scale bars, 12 µm.
